Whats better for performance and sound and all around for your car?

HI Flow Cats or Test Pipes?

WHY?

 

Test pipes sound nice in my opinion.

 

Thanks jamesond19.....come on, no one else has input

 

test pipes make it raspy. some people like it some do not.

Hi flow cats is less raspy. some people like it some do not

You wont pass emission with test pipes, but you will have hi flow cats

 

which is better performance wise. Id like to get more sound out of it, but definitely not into the ricer crap.

 

test pipes


cats


performance wise, you wont get much improvement. our powertrain is just hard to get power from NA.

 

Seems like I've mentioned this a few times before, the most restriction is in the OE cats so without rasp or having your G impounded for removing smog equipment it's best to go with HFCs. They're 49 state legal and will give you no less than 10 RWHP, not bad for under $500....

ART pipes. Best performance, no rasp, reduces drone.
