3” down pipe with dual up pipe
I ordered the dual up pipe and 3” down pipe kit for my 2015 GMC Sierra SRW 3500. The fit of the pipes was just like OEM. The kit did come with new bolts that had nuts with them that I could not use because they were the wrong size so I ended up having to use the original bolts. After getting everything back together the first start up sounded like success! There was no longer an exhaust leak and the 3” down pipe made the truck sound better. I would definitely buy this kit again if I had the need.
