(1999 – 2018) Chevy & GMC Silverado / Sierra 1500 / 2500 **Downpipe Kit Only**


This is the downpipe kit for our standard T4 GM Truck kits from 1999-2018, it utilizes a stepped 3.0- 3.5″ downpipe. This will be sold with an option for the downpipe only and also with the mid-pipe and straight section depending how you select it. If you opt for the midsection, it will include the clamps needed in the upgrade price and will come with everything photographed. If you select downpipe only, it will not come with any clamps.

We have been receiving a lot of calls looking for these lately for various reasons and we have a few extra downpipe kits by themselves that we are going to offer outright. So if you are one of the guys that modified your downpipe to a hood exit or fender exit and are wanting to go back this is your chance. If you are a customer that built your own kit and your turbo shares a similar location this may be able to save you sometime on fabricating the downpipe.
