Yay, I Just Got My Roe Hi-Flow Cats Installed!

[Vipuronr]

Finally had my Roe Hi-Flow cats installed and picked the car up today before the rain comes! Its louder and sounds much more like what I think a Viper should sound like!

When I have a chance I'm going to post the before and after sound clip.

I have to wait a bit before I do the next mod, but okay, I'm happy today!

Do you still have stock exhaust behind the cats? I'm going down this road right now and trying to figure out if I can do it in stages or should I just do it all at once, (headers, high flow cats, corsa/borla exhaust) Haven't decided on which cat back exhaust to go with yet. Thanks for the info. Jeff

 

[Zentenk]

Grats, can't wait to get my high flow cats done... can't stand the stench and the obnoxious ricer buzz.

 

[Mopar Boy]

Glad to hear you like them! It really is day and night.

They end up with a good snarl eh?

Mutt - Depends on a few things. One of them is labor. If you are installing yourself and don't mind spending many hours assembling every time you get a new part, then do it in stages.

I got my car with a borla catback. I just did the roe high flows last summer. Will eventually do the headers too. For me it works as I have no labor bills. If I had to pay someone to do it for me, would do it in one shot.

If you want my personal experience I bought RandomTech High-Flow Cats and Corsa Exhaust at the same time and had them both installed at the same time. Price for both parts came to around $2,000 and the labor was around $800 for the install. I would personally do both things at the same time for an overall huge sound improvement and a little rwhp gain. I've always wanted to do headers too, but at the time I couldn't afford both, but am finally doing headers this summer. I'll be getting the American Racing Headers and replacing my current RandomTech High-Flow cats with the American Racing High-Flow cats. Also, I test drove a 97 GTS 3 years ago that had a Borla Exhaust. I personall disliked it...way too much interior resonance, your ears were ringing constantly and you most likely won't be able to hear music. I'm sure a lot of you will say you don't care about music, but I do since I'm an audiofile. The Corsa Exhaust is perfect, it sounds great, and ZERO interior resonance. It's also still pretty loud, but more soothing at idle and daily driving than other exhausts. Plus, you will hear the car scream when WOT!

Here is the video clip, thought it would be better because we have an HD Flip camera, but best I could do right now.

Poor picture quality but sound is right. Will probably do over more like the before pic. But, what I notice is the lumpiness of the cam is more noticeable and it is louder and "throatier" (rumbles)...if that is the correct word. I've had cars with headers before and though not that apparent, I do pick up a little bit of the header sound now ('98 was first year of factory tube headers). Anyway, I really like it now!

 

[Vipuronr]

Mutt, I have a muffler delete for the rear section, pretty sure it is Fitzgerald Performance, but might have been from Snake Oyl. Either way, it is the muffler delete with small bullet resonators at the ends before the chrome tips. Tends to give it a nice deep note. With the hi-flows, it is louder and seems to rumble a bit more which is cool.

If you have the bucks, do it all at the same time. I only do it piece meal because we limit the funds for modding the car...lots of other priorities. I'm happy with the sound, cam sounds real lumpy at idle (can hear in video). Doubt if I will go for headers, but there's a slim chance. More than likely will do Harland Sharpe rr's next.

 

[eucharistos]

congrats Vipuronr you demonstrated great patience

i do these mods in stages (unless like robert said, it is a "as long as we are here situation") so it is like getting a new car over and over again

Mopar Boy, thanks for the info, I'm an aircraft mechanic by trade so I don't think it would be too technical for me, I'm leaning towards the Roe hi flow cats and a Corsa cat back system and then American Racing headers later this year, who has the best pricing on the cats and Corsa exhaust? any idea? Thanks for the info. Jeff

Hey man, I know you already have everything planned out sorta, but if you are now considering headers possibly by saying there is a "slim" chance lol, I would definitely do that before the Rockers. You have several options to choose from in regards to buying different headers too. You will see a significant difference in rwhp and sound by adding headers to your car over just adding Rockers. But like Tony said before, if you have exhaust, headers, intake, tune etc., and then add RR's you would benefit from adding them more then. I'm doing the American Racing Headers with their High-Flow cats, but I do know the M&M Headers are considered very good and a lot cheaper. If you were gonna spend $600 on Rockers, I would just hold onto that money and until the funds are available put the rest towards headers.

M&M Headers

American Racing Headers

 

[Vipuronr]

I would definitely agree! If you are planning at some point to do headers, then I would do headers along with the rest of the exhaust (not like me). I've heard the same about the M&M headers and unless you have a thing for the more expensive headers, M&M's would be a good choice.

For Roe hi-flows, I went directly to Sean's website - Roe Racing - and ordered them directly.
2 1/2" or 3" Direct Replacement High Flow Metallic Substrate Catalytic Converter Set, 1992 - 2002 - High Flow Catalytic Converters - Roe Racing

If you like working with Jon from Parts Rack, a great source, you could see what his price is...he can get most anything. He also sells the Corsa cat-back system, if I'm not mistaken.

Hope that helps.

I wonder how the Roe High-Flow cats are compared to the American Racing High-Flow Cats? Either way, the rest of your setup if you do go with it, sounds like it will be the same as mine since I already have Corsa Exhaust and plan on getting the American Racing Headers. Good choice

I got my RandomTech High-Flow Cats(which I will be getting rid of) from JonB for around $300-$400, I forget. I bought my Corsa Exhaust from him as well in the $1600 range, I believe he is still selling them for around the same amount as well last time I checked.

 

[Vipuronr]

Well, what I learned from exploring the whole "who's got the best cats" issue, was it is difficult to decide because pretty much everyone says theirs is best. I believe, after talking to many, that they are all good - Roe, RT and Belanger. The thing about Roe, is his is an "install ready" with the extension pipe already welded (he does this when you order it). Plus, he offers a metal substrate that is quite good and his customer service is excellent. I looked at the Belanger as an example and all the pieces were separate. If you wanted something welded, had to get that done...assuming most people don't have an arc welder laying around!

On the headers, like I said, I'm not ruling out but it may end up being more than I can spend on any one mod. I will discuss with Chuck, actually all three - rr's, gear change and headers - to get a sense of "all in" pricing for the three. If I decide to keep the car basically original, then that would knock out the headers because its harder to change back.

Just a different perspective on having this particular car, why I bought a bone stock/low mileage car as opposed to one that was modded already.

 

[Zentenk]

Depends, I am picking my high flow cats based on cells per inch and found some that are 100 cells per inch which is the best I have found. I think Random Tech is 300~ or more cells which is more restrictive.

Ask Roe and American Racing how many cpi their cats have.

Well the AR Headers and Cats you can buy together or seperate, so I'm buying together which should be an easy install once bolted on to my Corsa since I already have a 3" inlet which I was told measures up perfectly with the AR High-Flow Cats.

I understand what your saying about possibly deciding on wanting to keep your car stock since originally it was the reason for wanting to buy a bone stock/low mileage car, which is also why you are uncertain about doing headers.

I guess I'm different. Since I too wanted to buy a bone stock low miled Viper. However, I planned on modding my car before I even got it lol. Only reason I wanted a low miled bone stock car was so I knew the car was well kept and didn't have to worry about previous owner tracking it and possibly running into problems later. I was fortunate because the previous owner barely drove it. The car had 9181 miles when I got it on April 8th 2008, and currently I'm at about 27,600miles 3 years later(7 more days will make 3 years to be exact). So I definitely made out when buying my car, also considering the original owner already paid for the Venzano interior so I basically got that for free

 

[Vipuronr]

I picked mine up around the same time as you - May '08. Mine with 5,200 and the car lived its whole life in Boca Raton. The car was only driven maybe 500 miles a year (avg), but it was pretty much what i was looking for. Originally following a '97 B&W, but when I was actually ready to buy...it was sold!

The car I bought came up about the same time and I really like the low look of the RT, so I bought this one. It was a toss up as to yellow or red, but I do prefer red by a slight margin.

I would love to put a Roe SC on the car, but the cost is just not within anything I could do...even used. So, I do light mods as I can, but really enjoy the car for what it is. I put it in a few shows, though I'm not big on shows, and took best in class at the last one.

Anyway, sorry for rambling!

Oh, by the way, do you have any pics of your interior you could post...would love to see what they did!

Thanks.

 

[Zentenk]

That is awesome, I picked mine up in Nov '08. I flew to NY and drove it back to DE 6 hours. He didn't take very well care of it and drove it a lot. Nothing wrong with driving it so long as you take care of it.

I was so scared to drive it home... (rainy day) haha.

I do have some photos of my interior. I'll have to upload some from my Blackberry when I was at an exotic car show last summer. I'll try and get them posted on here in a few. I actually spoke with Tony Venzano himself a couple weeks ago. Apparently my interior is the only one he's ever done on any B/W Viper. So I have 1 of 1 ever made.

 

[costanZo]

I actually found some photos of my Interior I took back in May of 2008 on my facebook which I posted below. I also attached 5 pictures to this post from the Car Show last summer

Thanks for posting, very nice! That's cool that he only did your B&W, makes your car quite unique!

I did not drive my car home, had it shipped up. We decided it wasn't worth the extra money to have an enclosed trailer and the car arrived relatively clean and unharmed. But, I did notice that the carpet was wet and assume it rained sometime on the trip up...knowing how water tight the Viper RT is...

 

[Vipuronr]

Well, I re-did the video clip of the exhaust after install of Roe cats...these are metal substrate cats. Its a Flip camera, best I could do, did it three times and this is the best of the three! For some reason, it distorts the width of the car on this site, but not on the video. Also, sounds a little louder in person.

I looked up the American Racing Headers/Cats on their website:

American Racing High Flow Cats: 200 cell ultra high flow metallic substate cats.

Which High-Flow Cats are you referring to that are 100 cells per inch?

Thanks man, yea I thought it was pretty cool to find out, I had the only interior like this. It was one of the reasons why I bought the car, considering the low miles too and how it was only a 1owner car. Must be nice to have your car back now tho so you can enjoy it! I hope the snow is finally done for the year haha.. I heard tomorrow might lightly snow... I hope it doesnt or it at least melts in the same day...

Have you figured out the Rocker/pushrod situation you're going with yet?

 

[Vipuronr]

Thanks, yes, cool interior! Weather here today is not nice, wet outside, cloudy and cold. Weather was nice on the weekend, but was just really busy with family stuff! Hoping we're done with snow too, as I would really like to clean out my garage starting with moving the snow blower to storage in the shed!

Spoke to Chuck briefly, didn't get into any details, but looks to be HS with whatever hi-strength pushrods go with them and fit. He says have to put the rockers in, then measure to get the correct pushrod size. Now just need to get sense of overall cost from him, and then get the money set aside!

This was a fun thread, thanks!

Hmm..interesting. I was going to order the pushrods with the Rockers at the same time, but he will have to measure the Rockers and overall setup first before deciding on what size pushrods to buy? I'm gonna be having someone install all my stuff that's an hour and a half away. So I wanted to buy everything first and drop it all off when I drop my car off. It was either that or ship everything to him, but he will still need my car so I figured I'd have my dad follow me up in his truck bringing all the parts.

 

[plumcrazy]

yes, pushrods get measured when you install the rockers. then you buy the correct size pushrods

 

[costanZo]

I got some cats from Mandrel Bending Solutions. I have not received them since ordering them a week ago, so... I hope they didn't rip me off. same with my bassani mufflers from Sacramento-mustang.com

I'm sure you will be fine, let us know how everything goes...

I'm still undecided on what I'm going to do. I haven't been this stressed in awhile trying to decide which headers to go with... I currently have the RandomTech High-Flow Cats which I was told has a 300-400 cell count. I have no idea what the Belanger Cats are, but I was told the Roe Racing's cats are 200 cell count and from American Racing's website, theirs are also a 200 cell count. If I decide to get the American Racing headers, I will most likely purchase their high-flow cats to go along with the headers since they have a lower cell count. If I get the Belanger Headers, I will probably end up keeping my RandomTech Cats unless the Belanger Cats happen to be a lower Cell Count.

I was just told the lower the cell count, the better performance and the louder the sound. In my book that's worth switching to another Cat. Unless the difference is extremely subtle, I'll just save my money and keep the RT Cats I currently have.

I was also told that these Header companies don't produce their own cats anyway, so they could be getting them from anyone. However RandomTech is a well known American brand so you know what you're getting. I just really want the lower Cell Count, if it infact matters

Alright, good to know.. thanks Plum for your wisdom
