View Full Version : stock muffler/resonator and 2.75" piping?

12-04-2007, 09:09 PM
Just wondering how hard will this be to do?
I am pretty much looking for a quiet exhaust, im not shelling out $1000 for a premade.
I dont care so much for sound, just dont want ANY drone.
So is it possible to do a 2.75" piping with teh stock resonator and stock muffler?
(although anything is possible, how difficult would this be?)

you kno that might sound even worse like a broken car. large piping going into a small muffler..

if you want quiet and flow

then get 2.5'' piping, turbo back. use a magnaflow muffler of your choice at the rear, and install an as-long-as-possible resonator from magnaflow somewhere in the middle. heres a good one: http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=506

buy the muffler and the long resonator, have a shop weld it all up. under $400 is my guess

my APR exhaust was quiet as shit, same basic setup. 2.5 inch piping, 1 resonator, 1 muffler. like stock quiet. so i removed the central resonator. it has a really nice tone now.

hes going BT so 2.5 isnt going to be big enough

I paid $315 flex back (including a new flex pipe) with magnaflow muffler and silverline tips. That's what I'd do. Big piping into little piping would sound aweful, and look terrible.

Also, I asked for 2.75 at the best local muffler shop, and they said they didn't have it. My options were 2.5 to 3in

Plus the stock resonator and muffler are bottlenecks.

I'm running 3" turboback with a magnaflow center resonator, from there to the bumper is OEM S4 piping / muffler. Definately a power loss with this on compared to my previous 3" straight thru muffler.

how does it sound? how noticeable is power?

I think I posted sound clips before, search and see if they still work. Its pretty quiet though, at idle you cant tell theres an exhaust and at full boost it sounds mean, louder than a Borla at WOT but like stock cruising / idling.
