Just got a used evo catless w/scooby sport dp & vishnu up... Curious as to what i could do for a cat as i am worried about big tickets and pollution guilt...
just curious if anyone has this setup and what choices you made......

 

Random Technologies has a midpipe with a high-flow cat.

 

would there be any downside to running the cat on this system?

 

It might cost you a few horsepower, but your car won't stink and you'll have a better chance at passing emissions.

 

passing emissions with just the factory third cat will be very hard.
ive read from other members that even when they swapped out the 3rd cat with a catless midpipe they didnt notice any difference in power.
