don't know, but you better find some good 02 sensor simulators to go with it. this advice is given for off road use only;)

Yeah. Its called an off-road H pipe, and almost any aftermarket exhaust manufacturer offers one: Corsa, Borla, etc.

Realize that:
- it is illegal -- in states with visual inspections of emissions equipment you will likely get caught, in states without you probably won't

- on a stock LS engine is generally hurts performance slightly to remove the cats: the engine's cam and timing are designed to need a certian amount of backpressure.You will hear people say differently but not those who have actually measured the results on a dyno. On heavily modded cars removing the cats can bring you an additonal 25-30 HP (I run the largest size available on mine and removing them will add 25-30 RWHP, but I still run with the cats.

- if you remove the cats have the engine re-tuned (the ECM re-programmed), removal can result in the car throwing some codes sometimes or running a bit lean at times, both of which are not good.
