Even if the ticket is a no-point ticket, you still have to fix the problem and take the car to a referree station for visual scrutiny. That is, if you live in one of the states that has the strict laws... It's a pain in the butt - it seems like they will get you at the mose inopportune time possible - about to go on a long vacation, car's registration is almost up for renewal and they won't renew without sign-off, etc. For me, it's CARB listed parts only - the best that I can get. Smog check headaches seem trivial - until you get one. Then, you're getting told what you have to do to your car by what date, pay fines, get on their 'watch list' for future smog test registrations, etc.

Thanks for the tip, I'll check it out; because I'm telling you, I don't know how anyone would put up with those fumes. I am not known as being sensitive to obnoxious fumes. At least not ones that I am responsible for !

I have an SRT and have deleted 2 cats and corsa exhaust. I dont think its too loud, I love it. It could be louder for sure. Also I have only smelled unburned gas or egg type smell less than 5 times ever and I have a convertable! I think keeping 2 out of the 4 cars gives you alot of advantages.

Jim,
Picked up the car and am on my way back from California today. I have the Corsa's and Roe High Flows. I'll get up with you soon so you can check out the sound. No unburned fuel smell, and I have no real reference on the sill temp. After a hour and a half drive, the sills did seem very warm. Inside cabin temps are warm too, but I think that's just part of the "love".

Rear exit here...
rear exit here as well, there is no smell inside but if you roll you windows down during a red light you can smell it especially if the wind is blowing...

B SNAKE 1 :
Thanks VERY MUCH for the tip ! I found that both exhauster vent flap assemblies were loose and had fallen away from the opening from which they are supposed to keep exhaust out. I snapped them back in (real loose fitting - not good design) and took the car out for a drive. It is very liveable, smell-wise, now. Noise from catless is still more than I like for street driving, though.Here is a link for those that want to check out the exhauster vents: http://forums.viperclub.org/illustr...cs-included-bad-ones-cause-exhaust-smell.html

Those going with hi flow cats, what brand is recommended? Random Tech, Bellanger, or ???
Catalytic Converter Simulators : 96-02 Vipers - Oxygen Sensors and Simulators - Roe Racing I have had these on my car for 6 years now no problems.

No cats in my 98 GTS. Borla exhaust out the back. No codes, no foul smell and nobody has ever mentioned anything about the smell when they get in so its not just me. I love the sound and decell popping and also love the cool side sills. The car had highflows on it when I got it and they still made a ton of heat. It was a huge difference heat wise. Try it. If you dont like it you can always add the highflows back in.
If you have exhaust odor in the car it is not just the lack of cats. It is an exhaust leak created when the cats were removed. The human nose is not going to know whether you have cats on the car or not. That is why the epa checking station have to use sophisticated measuring equipment
Get behind a large commuter bus, they are as clean (EPA) as can be - do you smell them.

If you smell exhaust fumes from the rear of your car you are driving way too slow and should trade it in on a prius. GTS Bruce
Has anyone noticed if their chrome bezel around the gear shifter on the center console gets hot? Thats where my forearm sits while my hand is on the shifter. I recently got new exhaust and catalytics - and I don't remember the center console getting so hot - so I'm thinking there is an exhaust leak ????

In a GTS the cats are inside the sill (I assume they're there as well in an RT/10). How would anyone know - for sure - that there were no cats....versus cats that weren't functioning well. You'd have to pull the sills right?

Just curious about the odor that some have and some don't with cat deletes... Does anyone remember pre 1975 cars before cats...
I would have to think that a fuel injected modern design engine with unleaded gas would still be better ? What I recall is that cars never smelled until they started putting cats on and those first cars with cats almost always smelled like eggs with the cats...

How much more power would you gain from doing something like this? The thought of more power and the car naturally sounding louder and meaner sounds great to me, but in regards to passing inspection, I'm assuming this is something you would have to put on and take off at least once every year...

My car is registered as collector so it's exempt from smogging... The main objective is to eliminate the heat when I get my sills resprayed so I don't have to worry about discoloration and bubbling and my wife burning her leg.

I'm assuming my car isn't registered that way then... I'm actually not sure, if it isn't is there a way to change this so I could have it re-registered as a collector? I was planning on getting headers to increase HP and sound, but this definitely sounds like a cheaper solution for the moment, so I would very much consider it. I just don't want to worry about getting pulled over, any tickets or not passing inspection.
Anybody got stock headers, and Belanger Cat back exhaust?
That's my set up at the moment, and I cant make up my mind weather to go for Hi flow cats or No cats? I have a feeling that if I go for no cats, the system will be VERY LOUD!
I can't afford headers so there out for at least 18 months
Any advice?
Cheers Mark.

I have stock 01 headers, no cats, and Belanger 3" exhaust, sounds great. Its loud, and the drone is annoying on the highway, but I just turn up the stereo

Anybody got a sound clip of "Drone" ?
I don't know for the U.S. and its different states, but here in Ontario they have random (rare, however) roadside spot checks conducted by the MTO and ministry of Environment. Inspectors will comb over your engine and undercarriage, and may also conduct a "sniff" test by a computer to verify that all is stock for that model and year. Any emission modifications will land you in trouble. This is the reason I have not gone catless. They can seize your car, and/or invalidate its registration until it is switched back to stock. At best - you get fined. I thought this was all heresay up until this spring - when they had a roadside spot check in a little town east of Toronto. They were really floggin a guy in a modified Trans Am. Just another example of Big Brother pushin' his thumb down on the common enthusiast.
