Hey everyone,

I recently started looking into exhaust upgrades for my Duramax build and have been going back and forth on whether to pull the trigger on this mod. I've heard a lot of good things from guys who have made the switch and noticed solid gains in both performance and exhaust flow.

My main concern is whether installing a high-flow L5P downpipe is worth it without also upgrading the intercooler or tuning the ECM at the same time. Has anyone here run this setup on a relatively stock truck and seen reliable results?

Would love to hear what brands you went with and how the install went.

 

thanks in advance for any help
