I am looking to replace my cat with just a straight pipe. I was wondering if i could buy any stainless steel pipe and smack it on or does anyone know of somewhere that sells this specifically. I will still have my stock headers, downpipe, and muffler. thanks

you shouldnt have headers....
s70- is there any o2 sensors he has to worry about around the dp, cat section if hes replacing?

1. You don't have headers. What you do have is an Intake Manifold and an Exhaust Manifold.

2. Why do you want to remove the CAT? Is it legal in your area to do so? If not DON'T DO IT.

3. Running a straight pipe on a stock system wont net you much probably. If you want real gains upgrade the downpipe and catback system in full.

4. I believe there is a 02 sensor on the downpipe and one either right before the CAT or right after the CAT. If you remove the CAT it is going to screw this sensor up. Your going to have problems and it just isn't worth it IMO.

*FYI spend the money and have a real turboback system made for your car or spend more to get prefabbed items for your car. You will be pleased.

ok thanks a lot guys
