If I remember right, Justin may still be wanting to detune his old truck. He had a set of Jammer 5's in there but he also has a set of 7 x 13's or something like that. Either way, the 5's have been in my truck and I pulled them. He would probably part with either set for a reasonable price. I'll ask him and let you know if he has a set for sale. You could come to town and we could stab them in about a hour or so. The 5's are 150hp and I think the others are like 175 or so. Either way, they will be a little warm without a turbo upgrade. The 5's smoked a little more than my 4's so I pulled them and put my 4's back in.
