 GM LML 6.6L Duramax & V-Band Flange at the downpipe only!

Note: This exhaust system will ONLY fit early 2015 models. Confirm before purchasing!

Mel's Manufacturing Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
Looking to make more power and increase your MPG on your 2011 to early 2015 Duramax? The 431016 & 432016 by Mel's Manufacturing is your answer. It allows you to remove the restrictive OEM exhaust system and replace it with a free-flowing 4" exhaust system from the downpipe back!  Just like all of Mel's Manufacturing exhaust kits, this one comes with all the required clamps, pre-welded contour-bent hangers, and stronger flanges to help you cruise through the installation process. In addition to increasing power and MPG, you will also increase flow, which will help reduce your EGTs! 

*Please read the "Notes" section before purchasing!

Part Number: 431016 & 432016

Features
  • 4" Downpipe Back Exhaust system.
  • Aluminized or Stainless Steel
  • Single Side Exit
  • Easy Install - Mounts to OE Hangers
  • Includes Muffler
  • Reuse the stock V-Band clamp
Notes
  • The turbo direct pipe on the 2015.5 models has a 3-bolt flange instead of a V-band clamp, so it will not work with this kit. These kits will only fit early 2015 models equipped with a v-band clamp off the turbo direct pipe!
