H&S Performance 2011 6.6L LML Duramax Straight Pipe

Here's a little teaser of one of our test trucks - a 2011 LML Duramax with the SCR / DPF / DOC deleted and turned OFF. The truck is currently running about a 50 HP tune so there is still plenty of power to be made. All tuning is done with our Mini Maxx tuner directly through the OBD-II port.

Stay tuned for updates on our progress!

@linkthemain they need to put a aftermarket 3" downpipe on it.. I did that with mine and it completely got rid of that screech at high rpm

@linkthemain you must have an awesome blender

[commiesarelame]

@xdayonx Yeah, its the new Garret VGT turbo. They both have 'similar' turbos. They are 2 stage turbos I believe.

@autolover3 Defueling the shift to take it easy on the tranny.
