2015 Duramax Exhaust Improvements??

[Amiodynski]

So, has anyone replaced the Stock exhaust? I'm not looking to blow black smoke, but I wouldn't mind hearing the Duramax a little more under heavy throttle. I know in general from what I read, doing an Catback exhaust is going to give you noise and a different tip, no improvement on anytihng else..

 

Thoughts??

About the only thing you can do without voiding the warranty is a DPF back exhaust, it will not change the sound though and is only cosmetic. To get any noise out of it you will have to tune and delete the DPF; bye, bye warranty. The diesel particulate filter on these trucks is what makes them so quiet.

^^what he said... I'm still mustering up the courage to void my warranty.. It will happen though!

Hmm, thanks for the feedback, looks like I'm keeping my stock exhaust and not bothering wasting the money on an exhaust.
