This is the Nameless Performance 3" Midpipe, is a great way to get extra horsepower and torque out of your vehicle in either naturally aspirated form, and it flows well enough for those of you who want to add forced induction.
Nameless Performance designed this midpipe with an aft-located 3" inner wound, outer braided, flexible coupler to ensure for a proper flange angle which will allow the axle back portion of the exhaust to hang appropriately and to allow for proper adjustment of the tip position. The midpipe also features a 4" diameter straight through resonator with a 3" perforated core to help smooth out the exhaust rasp. This is a two section 3" midpipe that connects with a v-band which makes installation more simple and allows you to clock the forward section of the exhaust to have optimal clearance.
Additionally, this midpipe is fully compatible with the factory driveshaft along with other one-piece carbon fiber driveshafts.
