Snug fit. Used all of the stock fasteners and piping, no exhaust pieces needed.
Haven't really gone for a testdrive yet... but I will shortly. I have to tie up the AAS or whatever sensor is in the stock box, and then I'll tear down the road. Not expecting a lot, but it should help the DP Tuner.

I also changed the oil (3.5 gal sound right?) and fuel filter.

So, if my wife asks: Yes, oil changes cost $200 for these truck, and I did not upgrade it at all. Next time... I'm getting the filter off the internet, instead of the $57 it costs at Napa... so I'll save $30 there. And I'll also get my 5w40 synthetic from Walmart... where it should be significantly cheaper than it was at NAPA for almost $20 a gallon. The fuel and oil filters were pretty cheap though, I guess.

 

I did 6637 a couple of weeks ago myself, it has got a cool sound but I think the muffler delete has gotta come soon. It seems like I got alot more of air in and it still seems restricted. I have the DP tuner with BTS valve body so it really wants to go but there still seems like something needs to be opened up.
