2012 Nissan Xterra and the aFe Exhaust.
As I have a lift available the installation went pretty easy, getting the stock system off took the most time,I had purchased from the Nissan dealer new gaskets as none came with the Exhaust kit and are superior (metal) to the after market gaskets I saw.The new system is straight forwards had help installing the 2 to 1 muffler on and then with a piece of 2X4 and a short sledge drove the Muffler on leaving room for the exhaust pipe which was a tight fit, be sure all hangers are engaged.
Great exhaust at a GREAT price
I am really happy with this exhaust system. I purchased the single exhaust system. Not only does my truck sound bad ass (exceeded expectation) but it also added power to my truck. The power boost is probably because I replaced a leaking exhaust with a bent pipe. Overall this exhaust is really REALLY good for the price. One of the guys at the shop that installed it compared it to a borla.
