Beware: Not all parts needed are included.
Purchased the single side exit Flowmaster American Thunder for my 2004 Nissan Titan. I was very disappointed to find out that there were no new flange bolts or gaskets. Worse yet, the band clamps included were junk, and would not tighten down enough to hold the exhaust together. I had to go and purchase 2 stainless 4 inch band clamps out of my own pocket for $20.00 each. I thought a complete Cat Back exhaust system meant "complete" For $600 plus, I expected more. Last Flowmaster for me.
