Hey everyone, im new to this forum. I recently purchased my first truck (2004 GMC Sierra 2500hd Duramax) Just here to introduce myself and to show everyone what I got. Im not sure what part of the forum this thread would be in, im not exactly used to this format like I am the third gen firebird camaro forums, but! Anyway my truck has an egr delete, 4" mbrp straight pipe to an 7" tip, airbags in the rear for towing, and an edge cs tuner.
