Doug Thorley Xterra Catback exhaust 2005-2015

Doug Thorley definitely took their time and paid attention to what works best on the Nissans. They designed this 100% bolt on system to provide the best power gains (10.5 hp and 15.25 lbs tq) and mileage gains while keeping the exhaust note mellow for even the most finicky drivers. A huge Nissan flaw is the very restrictive factory y-pipe and gigantic muffler. Thorley cured these problems by building a new mandrel bent Y-pipe with merged collector as well as eliminating the huge damage prone muffler and replacing it with a more compact free flow stainless muffler. The system consists of the new y-pipe, Mandrel bent tubing, stainless muffler, resonated tailpipe and all the necessary hangers and hardware for installation.
