I thought you guys might enjoy this. I am doing a set of injectors on an 04 LB7 Duramax for black smoke puffs at idle and a bit of combustion knock.
This is something that I just find really funny. "Hey, y'all! Let's put a 3.5" straight-through muffler on this Duramax to get rid of the restrictive muffler. THEN, we'll bend up this piece of 2.5 pipe to connect it to the original 3.5" tailpipe!"
