imdaman for a reason,lol yea pullin o2 always helps on solving tha cat problem i wana make it a how 2 write up, but who knos if any1 will approve it come on ppl:th_thumbsup-wink:

If the tech didn't hook it up to test backpressure, I wouldn't buy it either. Just unbolt the downpipe from the manifold. It's two bolts and will tell you for sure whether the problem is the exhaust or not.

never do this too much work and risk of snappin studs always pull 1 o2 sensor:th_nanana:

i never liked running my car without sensors that it needs to run, like the front o2 sensor.

u just take it out for a minute and take it around the block. just to feel the power gain, then you put it back in then go get a cat put on it works all the time, ive been doin it for a lil over 12yrs now. u can use a back pressure tester but half the tyme the cat is parshally clogged and wont tell u much.:th_yawning:

hell yea i wish i could get away with that here, no cat no problem

Yeah, no problem. Other than the fact that it's illegal. When the car is taken to the dealership they check for it. Also when the emission is updated during registration renewal, they check for the cat. Some small towns don't have to worry about it, but I don't wanna take the chance.

ive never had a visual check on my car, but they do hook it up to the OBDII scanner.

I'm getting set to change out the dp and cat on my commuter GT to 3", not sure where to find the best deal. I've changed out the front o2 over the course of 10 yrs. i drove it to work yesterday and the early morning and leaving work acceleration was horrible. Does the zzp 3" dp and cat come with gaskets, etc to hook up to stock cat back? i know about the $50 cat return credit for later purchase, I just want to get the best deal out there. Already spend some dough on 1/2 extension and 1/2 universal. DIY on a
Sunny Saturday. Shade Tree not Monster Garage here.

the 3" downpipe is bolt in, but im not sure if it comes with the gaskets. you might have to get those separate.

there is a dropdown and you can select the gaskets in the same window as the dp
