Downpipe 2015.5
Cam | September 18th, 2023
Everything was wonderful about this part I got it installed. There’s only one small issue with it, while I was installing the lower bold bracket mount it didn’t quite add up with the thread behind it. It was covering half of the thread hold behind it causing me to have to drill a hole in the mount bracket to get the bolt back threw it to mount.

JOHN (Alaska) | August 28th, 2023
Fit and finish was top notch. Install wasn't bad at all. Went right in through the passenger wheel well opening. All I had to do was move the DEF fill lines out of the way and it slid right in.
