does anybody have headers on there stock internal duramax. Was wondering if they help that much in the 500hp range and what they sound like.

Rttoys 09-02-2008, 05:51 PM Yep, have headers and up pipes on mine and I'm basicaly stock. No sound change due to my quiet cat and muffler, but the performance difference is huge down low and turbo lag is minimal all the way around.
