:crazy: Since hollowing out the cats on my 02 6 speed is not the advised way to go, how about swapping the cat pipe with the 4 cats for a Z06's with only the 2 cats?
Will it bolt up to the stock manifold? I'am sure that should make my stingers sound louder and possible power increase to boot.
Also will the stock 02 sensors be ok?
again many thanks. :cheers:
I changed my 4 cat system on my 01 Z06 for a used 02 H pipe and cats. It bolted up without any problems. I did not really notice much difference in the horsepower, but I did notice the increase in popping and burbling during deceleration. A recent accident resulted in unrepairable damage to the H-pipe and Cats.
:cry
For the right price I may try it again, but if you were giong to buy new, I think you could spend your money on other mods and see more return on your money.
