Quiet 4" exhaust?
Hi all, I'm looking for input on which brand (if any) has the quietest 4" system. I'd like to help the engine breathe better but because it's a company truck and is usually driving in residential areas, it can't be noisy. Thanks!

I have the 4" MBRP Turbo-Back 409SS system w/ muffler, and love it, definately a huge improvement over stock, and not much louder. (Maybe 10% louder) Biggest difference is more turbo whistle. Highly reccomend it, more boost PSI, lower EGT's, and a lifetime warranty on the SS systems.

if you want quiet...straight pipe it & throw a resonator in there. couple of buddies have real exhausts' like above, they sound beautiful, i've got the straight pipe thing, not as good sounding!
with a resonator & straight pipe it's descent. a couple other buddies did that on their 6.0s they like it

Magnaflow here also. I agree with Josh, not much louder than stock.
