I had speed engineering on my 08, and I'm getting a set for my new to me 07 classic. The fit and finish is quite nice. For the price, they are damn hard to beat. When you replace them get the MLS manifold gaskets like stock, the felpro fiber ones will leak. Dorman sells a replacement bolt kit too. I installed the headers and y pipe on my 08 while I was doing a cam swap but slid them in with the heads on, was quite easy, and the y bolted up well and I was able to hook it into my stock exhaust system very easily. Gave a nice idle rumble but nothing annoying at cruise speed. You will need a tune to turn off the engine light for deleting the cats and rear o2's. It will run just fine, just have the annoying light if you don't tune. The nice thing is these trucks respond well to a tune with no other modifications too.
