Need to quiet down my exhaust setup

N///M3 · 05-01-2011, 03:25 PM

I have my stock primary cats in, but removed my secondaries with piping, and have a super-sprint x pipe which removes the resonators, paired to a ac schnitzer race mufflers.

I need to quiet it down as there is a lot of drone and it is also too much noise for daily driving and having clients in the car.

Should i keep my acs race mufflers and put back in my stock secondary cats and stock x pipe with resonators or leave the custom mid section and go stock muffler?

Thanks in advance for ideas guys.

Stock muffler wont quiet anything up if you leave the midsection as is. It will be really raspy and loud and really doesn't sound any good

I would replace maybe primary cat in the mid section it will leave some punch and help it out. Secondary ones wouldn't be the best option

If you want some tone and no rasp then yes put back your stock mid pipes ... you will drop some HPs but it will quiet it down a lot.

Ok seems like all stock except the mufflers should fit the bill. Thanks fellas

since you gotted the 2nd cat, replace the 2nd cat with a resonator... its going to quite it a bit but not close to OEM
