The 3" mandrel bent pipe eliminates OEM restrictions and allows maximum airflow through your exhaust. The included OEM style 3-bolt flange makes installation easier than ever!

FLO~PRO 3" Turbo Direct Pipe / Down Pipe

2015.5-2016 6.6L GM Duramax LML

The factory turbo direct pipe on the LML Duramax's is very restrictive.  Unfortunately, due to the construction of the factory downpipe, none of the exhaust manufacturers include this piece with their full exhaust kits.  We offer this FLO~PRO turbo direct pipe that will bolt directly in place of the factory unit and give you a freer flowing exhaust.  This piece features stainless steel construction and heat wrapped to avoid any ambient heat overheating the firewall. 


  • This turbo direct pipe is only intended for fitment on 2015.5-2016 model year Duramax trucks which feature a three bolt flange at the lower connection point.  2015 and previous model year LML's will feature a clamp joint.
