Yay! Putting on my Roe Hi-Flow Cats!!! :)

[dave6666]

Non, non, au contraire mon ami!

I am not dissing any other brand, this was a comparison of Roe's metal sub-strate to their fiberglass honeycomb cat.

No comparison made or meant to RTech or Belanger...or any other for that matter.

Sorry if I wasn't clear!

Cats with a fiberglass substrate? You are joking right? If not, who makes them? I'd love to see the specs.

Dave, directed at me??? I got the full Roe hi-flow cat setup with extension pipe welded, metal substrate.

Yes, directed at you, in regards to your statement I quoted in my previous post whereas you suggested someone makes a fiberglass cat. I would like info on the fiberglass cat.

Here's what it sounds like now, with Fitzgerald Performance muffler delete pipes - consists of two small bullet resonators. ....

You can hear the light rattling at idle of the inside of the resonators...common after awhile. Chuck says that the Roe hi-flows should probably drown out most of that!

I hear that same rattling on mine, but I don't HAVE resonators! Belangers, RT HF cats and stock behind the cats. Any other input on what that sound is?

 

[Vipuronr]

Okay, maybe I wan't clear, oops!

I know the hi-flow cats come in metallic and CERAMIC substrate...I might have just written that incorrectly.

What I was talking about (or complaining about), is the sound deadening material used in the bullet resonators, which I thought was fiberglass...as in the "old days" of "glass pack" mufflers.

What it sounds like when standing in back of the RT, is at idle, some of the "fiberglass" is loose and shaking inside producing an (annoying) noise in addition to the nice low tone of the Fitzgerald muffler delete.

Hope that clears up and miscommumication.....

Mike...not sure what the sound is then, I just assumed it had something to do with the resonators.

 

[plumcrazy]

cant imagine fiberglass making noise. that sounds more like a metallic noise

 

[dave6666]

Your substrate may be loose in the cat did you shake them good before the install? Most guys do shake things some twice maybe before or sometimes after the install.

 

[Vipuronr]

So, two things then....the noise only started when the muffler delete with resonators were put on. Is it possible that the 8" (or so) resonators welded near the end of each pipe actually have metallic substrate (or whatever it is that's in there)?

If that is the case, is there anything that can be done short of replacing the resonators?

 

[dave6666]

Any resonator whether metallic or non metallic will at least have a support structure in there made of metal. It could rattle if a spot weld was broken or if it has a rolled bead to lock in a particular spot or whatever and it was distorted by a clamp or weld heat. Did they do any welding on your install or is it all clamped? Have you checked all your hanger rubbers and hanger to pipe welds?

 

[plumcrazy]

FYI, i replaced my resonators with Roe bullet mufflers

 

[Vipuronr]

So, my car had stock exhaust which I did not like, and Chuck had a take-off piece - the Fitzgerald Performance muffler delete pipe, which came with a bullet resonator near the end of each pipe and a chrome tip. Clearly, it wasn't new, but i couldn't pass it up.

As you say, something (weld or a bead) is loose and may be causing it. After the hi-flows go in, I'll decide whether this can still be heard. If so, might opt to change the pipe at some point.

Thanks for the comments!

....

some (all ) magnaflow's straight thru mufflers have stainless mesh instead of fiberglass, so it is possible your fitz's do too.

also, the way i understand it, resonators usually don't use baffling

 

[Vipuronr]

Well then, not sure why...but it didn't do it before the muffler delete pipe, so it has something to do with the pipe. No biggie, I'll wait until the hi-flows are on and see how it is.

Thanks all...oh, and another (almost) one foot of snow last night! Sure getting lots of use out of the snow blower!

Yeah, yeah, now they're forecasting snow for tomorrow and Saturday!!!

YAY, F'n YAY!!!

Now that really does sound nice Do you get hi humidity in the summer months?

My wife found out I bought a viper when she open the mail and saw our updated insurance card that included the viper

Sounds so familiar...as I did the same but wife realized i had purchased a viper after the car cover blew off it one day (parked across the street from my house).

I've heard Dallas is actually Southern Oklahoma and Houston is in Texas
Is there any truth to that

 

[Vipuronr]

Depends on what football team you support!

 

[Fatboy 18]

Vipurnor, Sounds like you need to get that car down to Dallas

Hell, get an enclosed trailer and tow it there

 

[Vipuronr]

Used to do work in both cities (near the Galleria Mall in Dallas)....like them both (political, huh), certainly the warm temps is an advantage when you want to drive your Viper....all I can do is start it, move it back 3" and then move it back up to turn off!

Sooner or later the snow will go away (probably later at this rate) and I'll get the hi-flows on.
