Hey y’all,

recently been chewing on the idea of a 4” axle dump exhaust…. Anyone know if it’s been done? I’ve searched the web far and wide for a video of 4” exhaust on these trucks and can find nothing. I’ll post pics if I pull the trigger on it.
I like the dump exhaust look and would add clearance from that ugly ass blunderbuss on the back. Only concern would be during regen, for the time being (however, delete coming shortly).

Haven't see one done yet. Yeah I think the temp may beat up the tire a bit but then again while running down the road with airflow maybe not.

here is the pics of the dump exhaust. Been on for about two weeks now. Noticing a slight bump in turbo noise, little more drone at highway speeds (been to Colorado and Montana from OH in the last week) and it performed great. Did some serious off-roading with it and would have definitely crushed the stock exhaust in spots.
