Injen Technology's Super SES line of exhaust systems are dyno-tuned to compliment their performance intake systems. In doing so, the Super SES provides maximum horsepower and torque across the powerband. The Super SES exhaust system is manufactured from 100% 304 stainless steel. Each exhaust system features CNC mandrel-bent stainless steel tubing, CNC machined flanges, and robotic tig welding. Removable silencers are no longer offered as they now come built into the muffler for a new hassle-free exhaust system. It's the new bolt-on and go, care-free system by Injen Technology.
