Looking for a single round 4 inch muffler for turbo build. Looking for a quiet sound. This car is driving on street and my passenger dosent like a loud glass pack sound. I will run a cut out for the fun days. happy wife happy life. If u could post sound clip and name and part number would be great. I pretty sure im looking for straight thru design????????? Thanks

Just buy the biggest one that will fit your car.

Job done. If it isnt quiet enough, fit another, job done.

I know the 4" Corsa DB series diesel mufflers sound pretty darn great on non diesel boosted trucks. Muffler is expensive though soo thats a huge downside.

form my experiences similar sized ones will be @ same loadness at wot, different tones at lower but same max db's, so find the longest, thickest width you can fit. The quietest, if you have room, is the big oval normal shaped mufflers, straight through design of course, they have 2 or 3 times the packing, plus i think that width makes it act kinda like a resonator but id.Same thing but without the fancy chrome

or just scream "***** dont drive this car!" next time she complains, lol.
j/k its a line from a movie

I have the 3" version of this on my car along with a cutout and its super quiet. Sounds stock out of boost.

Buy a tape measure. Go and measure space available on YOUR car, then YOU decide what will fit.

As I'm several thousand miles away and cannot see either your car or the space you have available, kind of hard for me to recommend


What other info do you need really ?

And with testing both chambered and glasspack style on my own car, the glasspack whilst straight through perforated tube design, definitely reduce noise much better than the chambered one I tried.

Got the 4" corsa diesel muffler on my gas truck and love the way it sounds! Also it doesn't kill turbine whistle like most mufflers because there's NO packing in it. I think all corsa mufflers will allow you to hear your turbine whistle out your tailpipe.

How rad.is your engine ? Most stock turbo builds dont require much of a muffler anyway.

FWIW-I just ordered the dynatech cone inserts in 4". Mine is pretty loud with no muffler but doesn't really bother me. I worry every time I drive by the cops though. I throw it in neutral and let off the gas and coast. lol I just want to kill the sound a tad. I will let you know how it does. If it even works at all.

Dynomax sells an ultraflo round muffler in 4"

multiple mufflers with an e-cutout. Best of both worlds.

I like Magnaflows a lot. Dynomax is good too. Straight thru design.
