like it says, i want to lose the cats, but i dont want the horrible smell, i did it on a 95 mustang a few months ago and it was terrible, when you pulled up to a stop light it would almost make you pass out and everyone around you was pissed at you, but it sounded awesome and ran like a bat out of hell. even my 71 mustang doesnt smell hardly at all, is there something i can do(get the computer tuned maybe) to make it not smell so bad

my '91 vert is catless and has a side exhaust(will be changed as soon as I can afford it....) I dont notice too terrible of a smell other than an average smoggy smell when at a light with the top down or if its been sitting a while. I still have my smog crap hooked up... so I dunno....

My friend has an 87 with no rubber sift boot, or boot cover. and he has a little exauhst leak where the mids connect to the headers...lol. I literally get high in his car. that carbon monoxide cant be good for me.[:'(] His car sounds pretty beefy though. But I have the same bbk x-pipe with cats and it sounds exactly the same...so I don't know.

If the cats are not in place there is no way to really reduce emissions to federal standards to avoid the smell.....removing the cats won't reallt affect a/f mixture on your car cause the o/2 sensors are before the cats so there is no real effective way to lean it out unless you had a stand alone tuner to constantly monitor a/f to keep it in safe levels

same here, Im thinking an exahust leak is to blame

The only difference I felt was in the pedal. It wasn't really louder but it had more of a rumble to it. If you stood next to my car and I rev'd it to 5k, you would feel it in your chest lol...

It's worth it.. they're cheaper and add horsepower. Right there I'm sold. I obey the laws, but cops let the damn motorcycles haul *** down main roads and then try to ticket me cause my car sounds badass and your jealous..

I'm catless & the only thing that stinks is trying to get an inspection each year as my state mandates them

i think you have a leak somewhere my 85 was catless and it didnt give off any fumes, getting ready to go catless on my 88 GT for the better sound.
