Right now i'm running a big turbo setup with a 3" open down pipe, and the sound is ridiculously loud.

I'm thinking about getting two Magnaflow mufflers, one inline where the stock resonator is, to act as a resonator itself with the 3" diameter matching the rest of my exhaust, and a regular oval for the rear.

Does anyone here have experience with an exhaust setup like this? Obviously this way is more expensive, but is it worth it?? I want it to be as quiet as possible without hurting flow too much.

 

My 3" with one oval 18" Magnaflow at the back is really nice. I have a Vibrant Ultra Quiet Resonator I had intended to put just after the DP, but I decided it's not necessary.

 

I have a 2.5 back no cat vibrant muff just put in a inline magnaflow muff and definitely helps keep the noise down. It is almost dead quiet idling.

 

I was running straight 3" Ex, and it was crazy loud,

for me I used streetpower oval vibrant muffler, it was day and night difference in the sound...

so, vibrant is my advise for you...
