If you want to remove them, it is better to replace them with pipe, if you just punch the brick out of them, you will end up with two empty chambers that will lose you some low end torque.

p.s. Do you know that Lions brewery is trying to buy Coopers, this must never happen.

Yeah, I figured that the CATS were definitly a part of the Exhaust design and that if I removed the materieal I'd loose that torque down low that gives me the advantage over a good number of WRX's on the AutoX course.... The thing is though, What to replace them with??? Straight pipes are pretty much out of the question. That changes the exhaust even more... Replacement "High-flow" CATS sound like a great idea, however they are so $$$$.... Does anyone know of a High-Flow CAT that will fit where the two primary CATS are on the SVX??? I'd prefer an all Metallic CAT (Like the Random Technoligies CATS) that flows around 400cfm and that doesn't cost an arm and a leg...


Harvey, I didn't know that coopers was up for sale!??!?! That's terrible!!! !!!!
