Ok, we have all seen the votes on the most popular exhaust, but what is the quietest exhaust so WIFE can't tell???

 

[nct]

probably banks or corsa (TTS)

 

[bcarricarte]

Only go with banks. Very NIICE!

 

[Diesel Tech]

We've got you covered for the quite exhaust.

Stock. If you want quiet with ANY system keep the cat and muffler.

 

[DMAXXED]

I got the Magnaflow turbo back and its quiet on the inside. Don't know on the outside.

 

[Horsepower Upgrades]

MBRP Cat back for sure, at idle you may not even notice. Call if questions.

You will not be disapointed

If you choose the TTS exhaust. I know I was not, and the sound level to stay quiet was top on my priority list as well.

TTS cat back all the way. Can't tell it from stock even when pulling my 9200 lb travel trailer up a grade. Also about a 100-150 degree drop in egt when towing.

my turbo back cool duels are loud when it starts, and wot, also made the turbo MUCH louder. so dont get this setup unless your wife is deaf.

banks

I have the banks system and difference only noticeable to the trained ear. There is a louder turbo noise and exhaust is a bitlouder outside when towin. A great system to drop egt's while keeping noise level near stock.

Same here. It is just louder than stock but has a good amount of turbo whistle

Who wouldn't wanna hear the Duramax roar!?!? ):h

 

[DuramaXXXin]

Had the Banks before, the only reason I changed is because it was too quiet for me. So from my experience Banks would work for you.

 

[Badgersam]

I already have a 4" exhaust turbo back and like the sound at idle, but hate the "drone" at cruise, It was bought off e-bay by the previous owner, so I am looking to just buy a muffler, not turbo back system, any suggestions?

 

[gs300zx]

I've put on the Banks cat back and can't tell except for the exhaust tip that it's not stock. 2006 LBZ

 

[T-Rex]

Corsa is as quiet as stock.
Excellent fit.
Expensive.
Unique tip.
Boring quiet - no drone whatsoever.

 

[Z71offroader]

i have the 5" mbrp cat back and it is actually quiet, louder than stock but not annoying, alot quieter than i was planning, about to cat delete it to open it up.

for sure keep your cat and muffler, id suggest banks, nice system and quiet.

 

[Bodysurfer]

BANKS, very nice low sound....even when I put the MBRP front pipe on, it was still very nice sound.
