Sorry I thought I had a video but I changed them out for Mac's 2 years ago and all my videos from then are on my old phone.
It was cheaper. $60-70 each for the mufflers, $60 each to weld them up - tips, hangers, and all. Fit was perfect since the axleback pipes were never removed and the mufflers were held up on a stand then welded in place. Better fitting that way than any cat back or axle back I've installed on any vehicle. Only con would be the unpainted aluminized mufflers started to rust in the typical areas Flowmasters rust.
