    Cat Maybe?

    Alright, I got a new situation going on. I was pulling my cap off my cut out tonight and smelled what seemed like raw fuel coming from the cat. Rich mixture surely, but I was wondering if that could have fried my cat and made it useless. That could explain the problems with driveability i've had from time to time. Could it be the cat? I just want some other opinions besides mine. If it is, I will surely yank that sucker right off and run a straight pipe.

    if a cat is clogged it will make the engine sputter and not run hardly at all. if you have been burning leaded racing gas, you have damaged the cat and the O2's both. what issues are you having?

    running kind of funny, performance is still there, but not 100%, and last night I smelled something funny coming from the cat as I was capping the cutout. I had a friend that's cat just wen't out with 105k -- my cars got 125k. I replaced the opti with an Accel, did a full tune up- wires, plugs, the whol e shabang. I took the car out this morning and gave it a nice romp and now it's 100%. It's just wierd. Somethings making it inconsistant and I cant find the problem.

    i haven't heard 1 good word about an accel optispark. i hate to say that since you just put it on. hopefully it will last ya. if it starts showing its ass again open the cut out. it it clears up right away, you know the issue is the cat. if not, well you can guess where i would go first.

    He means that if you think its the cat and you start having problems again, open the cutout so the exhaust isn't flowing through the cat. If the problem disappears, then its most likely the cat.

    lol oh well there goes that way to check it then. 1 question. why would you put a cut out after the cat? unless you are running the stock y pipe, then i can see why. if you can get by with a piece of staight pipe, thats the route i would go.

    Simple. To bypass the muffler. You'll still pick up some power at the expense of a little low end, but not enough to cry about, and nowhere near as much as if I had cutouts right off the headers. As far as straight pipe i'm guessing you mean in place of the catalytic converter?

    I don't but I wish I did. Since it's so cheap and easy to do, i'm just going to yank the cat and weld the straight pipe and go from there.
