If i was too go with a high flow cat or test pipe, how do i clear the code? I have to replace my o2 sensor pass my cat anyways. It's a 97 therefore i have to pass emissions.

Also my cat smells up my car so its obviously bad. Cheap and some hp way out =]

if you go catless then youll need an O2 simulator. if you go high flow, you shouldnt need to trick the puter, it should work fine with out a simulator.

Yea I got a high flo cat on mine and there weren't any codes present

Which is easier? i wouldn't know what type of high flow cat to get. Any help or links off ebay or amazon.

well a test pipe is always easier. but more of a hassel if you have emissions standards in your state.

Yea if your state doesn't care about emissions then get a test pipe. But I'd get a high flo cat just to be on the safe side

yep i got a carsound (a brand of magnaflow) high flow cat

and to clear the code just pull your EFI fuse for about 30 seconds. works fine on my 98 v6. i have no cat and no o2 sim... one of these days i'm gonna get a hi-flow unit installed so i not only pass emissions, but also so the car doesn't smell like unburned gas when sitting in traffic or at a red light.
