Default 68mmstg2r - taming the f16 on kill sound

I enjoyed the straight pipe sound briefly, but it became a bit much for me, the neighborhood, passing aircraft, rock concerts across the bridge, etc. haha

I took a little time and I have kept some of the great sound, and tamed the rest. I know some that dd their rigs are apprehensive about the R for noise reasons, so I'm sharing a video to show that you CAN have your cake and eat it too. This setup is very pleasing in the cab!!

What I did/have:
3" downpipe
Injen Evo large airbox
4" mbrb exhaust with muffler
5" tip
Small fte resonator
Reinstalled oem air intake resonator box

This morning I started her and did a shut off and restart to show how mild the vane sweep whistle is now.

If you worried about noise - don't! This is a great setup if you want mild sound and tons moar powaaaaaa


Ok vid not uploading. Missing security token error on this site?! I'll upload to YouTube and link back ASAP.

The best way to tame the noise is put a big turbo after it

My wife's has a 4" Magnaflow system with their muffler and it is very quiet compared to a straight pipe version, I find it to be the perfect level of sound. Kyle's recommendation is the best one though!

I found that my profab manifolds and up pipes with the mbrp dp and the 5" MBRP dumped with a muffler is very quiet. Don't get me wrong she still screams but it idles alot lower of a tone. Neighbors don't complain much yet, we will see what they think in winter when it's on high idle

I'm trying to figure out a muffler for my STG2R. I want it to sound aggressive and don't mind it being on the louder side, but the 3"DP and 5" straight pipe is getting to be a bit much. I drive around 500 miles a week for work and I'm constantly on the phone.

I'm leaning towards a 5" plain jane MBRP but I'm still unsure... Maybe an MBRP "quiet tone"?

Any suggestions or tips?

I just made it home from a 7+hr ride; family vacation. This is a great setup for my needs. To be clear though - this is still a loud MF'er outside to the general public But with the windows up, she's a kitten inside with a nice little whistle.

Sadly, I've only got the stg2 3794...but she sings
I've got a 4" MBRP Turn Down exhaust and a 3" DP that IMHO is a wonderful combination...one caveat with my set up is I am a little higher off the ground than stock, so I think that helps with resonance issues others have talked about with the TD style exhaust, because I don't get any of it. I think the truck idles as quiet as any could want and has a nice throaty diesel sound when just scootin around, however ITS A NASTY S.O.B when the skinny pedal is buried
coupled with the insane performance whistle you get with a Danville charger, it's blissful to my enthusiast ear

Have had good luck with flowpro twisters on the R's. Work well to tame cummins down too
