I have a Dynomax Bullet on my truck (P/N 24222), sounds good to me. Not to loud but loud enough to know you have something and very little drone. I may change it up soon and go with the Carven "R" series muffler.
I don't see the need for a build thread. This truck want look any different anytime soon. Trying not to spend so much damn money on it, like I have on all of my trucks in the past.
How's the vibration with these tow mirrors? A few years ago I bought some off Ebay (kool-vue) for my d-max and they vibrated bad going down the road, finally had to put some stick on wheels weights on the back side of the mirror, it helped some but still vibrated alittle but not nearly as bad.
