How much will a Dual Chamber Muffler quiet down my car?
 

I have a cutout that I can open up when it's time to hit the loud pedal.

With my setup, I barely have enough room for one muffler and one Resonator. My muffler dumps in the middle of my car and it's too loud for my liking. My muffler is a Borla XR1 so it's straight through.

My question is, would switching to a dual chamber muffler quiet the car down quite a bit?

:wallbash:

well have a 4" setup that i originally did just a flowmaster 3-chamber only and it was WAYYYY too loud, put in a magnaflow racemuffler for a resonator till too loud. i have a second magnaflow race muffler im going to put in to try and get the DB's in check. havent checked to see if the chambered mufflers effect back pressure yet but im assuming they will even in the least.

Thanks, anyone else?

Probably about this much more quiet.

Every quiet rotary out there on the road is not making power, or at least not making alot of power.

I've got a cutout that I can open up in about 30 seconds if I need to make power. I guess I'm getting too old....... and when I find room back there to put a sub, I'd like to be able to hear it :)

Pipe that loud exhaust back to the intake filter and it will help muffel it also helps warm the motor in the winter!:dunce:

it will help to get it ouside from under the car, the noise is just resinating under your car and making it louder than it is. im sure it is really loud, but it will help the sound in your car to get the exhaust out from exiting under the car.

Just my .02

I gotta say, it sounds much deeper under the car. Still rattles the windows in my house though :(

Oh crap ! i just purchased a pair of XR1's for my FD ! I read somewhere that they do a very good job quieting down a rotary ! I this wrong ?
