LML Duramax 2011-2015
The HSP LML Downpipe for your 2011-2015 GM 6.6L Duramax LML will get you that signature Duramax sound you've been after. Constructed of 3" stainless steel, HSP's downpipes are built in high quality fixtures to ensure excellent fitment. Their design allows for extra clearance for aftermarket up-pipes without compromising the exhaust flow. This lowers EGT's and increases power while improving the exhaust tone from your LML.

3" 304 Stainless Steel Construction

Note: Will not fit 2015.5 and up models with factory 3-bolt flange downpipe. Please confirm which downpipe you have before ordering.
