yes.

Murk 'EM

it will make it a little louder but not much

MonkeyMagic

cat's help decrease noise... especially the pop sounds and some high pitched sounds

but the noise difference between high flow and a normal cat with same diameter inlet/outlet is 0, none, null, nill, zip

its gunna be louder but not raspy like a oversized bee is going down your street hiten mad V-Tec Yo.

high flow cat will make it sound a little louder without making it raspy.

A resonated test pipe will make it a lot louder, you will not be street legal, your exhaust will smell like complete **** and you'll smell it inside the car, and you will have hella raspiness.

It might make it a little louder but probably won't be that noticable. Remember that the muffler is there to stop the noise. If you had a high flow muffler on the other hand, that is what would make it much louder.

i have a skunk2 test pipe with no resonator and a dynomax exhaust and it sounds amazing!...love it!... lol.... might go with the hi-flow cat though...i dont want to see REF!...

We dont have emissions testing here im actually running a skunk2 megapower exhuast now im going to boost my engine soon i realy want to keep the noise down to a dull roar lol
i might actually be swapping out to a ws2 exhust or something quieter. and i forgot about the smell so i dont guess im doin a test pipe

so i guess its gonna be a high flow cat so what kind is good for a boosted app
