just got my pasetter lt's,new 3" mandral bent exhaust and new nelson tune in the av it went very well...about 5hr total with breaks and phone calls.. ..took it for a test drive and noticed my i dont hear my radix like i used too...it's quieter at wot.the new exhaust sounds bad ass also and " NO" in cab noise at all...that is exactly what i was going for and am very pleased the power feels good also but i know that the new tune has to relearn for awhile...anyway im glad i finally got them in the truck...they have been setting in the garage for awhile now...
