May get a little raspy

1MOREMOD · 10-01-2011, 05:03 PM

get rid of the cats and keep the resonators?

onnex · 10-01-2011, 05:15 PM

ya, it'll get more raspy for sure if you take them out. If you're not looking for rasp, I'd delete the cats.

1MOREMOD · 10-01-2011, 05:16 PM

cats out will make it more raspy also but not as much i dont think.

1sikbmr · 10-01-2011, 05:19 PM

delete the cats for a nice sound and bump in power.

probably. I ran a catless MXP pipe with 4 resonators without rasp. Now I'm catless w/out resonators and I have more rasp than I know what to do with

I'm guessing there might still be some rasp without cats and just a pair of resonators on the OEM pipe– can't say for sure though

DO NOT DELETE THE RESONATOR... TAKE THE CATS OUT.. YOU WILL NOT GAIN ANYTHING ON REMOVING THE RESONATOR... the only thing you will gain is a RASP....

I have active x-pipe with no cats with oem exhaust right now. (waiting for the muffers soon)

It is very raspy and loud when you get on it. (sounds like a dirt bike) If you're just cruising then its fine.

ugh... im having the biggest trouble deciding to have a resonator or none on my xpipe

resonator tone down sound along with helping drone/rasp or just rasp?
