2017 Silverado 5.3 Spintech New Setup

[Gorske]

Changed up my exhaust today. Still using the Spintech 6000 Pro Street 3" in/ duel 2.5" out muffler but instead of a side exit before the rear tire I had them run 2.5" pipe back and dumped at the bumper. I think it sounds better and it is quieter on the inside of the truck. Let me know your thoughts.

I've noticed with this truck if you rev it up it tends to hold the RPMs before going down. You can really notice it in the recent video.

Like how you change it from the front of the tire to the back... is it quieter now? I'm listening from a phone

Quieter in the cab but about the same on the outside. Seems to be a little deeper tone. I like it better how it is now.

 

Here is a cold start clip.

Sounds great! Interested in this muffler for my 2015 2500hd 6.0.

Could you post any in cab videos? Curious how loud it is inside the cab? Any drone? Thanks!

Curious. Resonator and flapper gone? What was the total amount you spent to get it out the rear including the muffler?

This was the old side exit interior sound. Quieter on the inside of the cab and less drone also with this new setup.

Yes resonator and flapper gone. Only thing left from the stock exhaust is from the manifolds to the flex pipe. Muffler is right around 120 shipped from Spintech, and the install was 150 by a local muffler shop.

Like the look and the sound much better out the rear bumper than before the rear tire.
