Finally got around to installing my diamond eye down pipe tonight, and it was a b!tch! I am envious to those of you that claim they have done it in 40 mins because it took me almost 2 hours and I like to consider myself decent with a wrench. Either way, it is done now and awesome! It totally eliminated the annoying screetching that my truck was making when I would lay into it hard. Seems like it spools a tad quicker and sounds waaaayyy better with my 5" straight pipe. I have to say thanks to Brian for coming over to give me a hand with it tonight :hug:. For sure made the install easier with his help. I would recommend getting an after market DP for those of you that don't have one yet.
