Description
The CORSA Xtreme Exhaust System (manufacturer part number 21077; Summit Racing part number CSE-21077) is a dual-exit, rear-center axle-back kit made from natural-finish 304 stainless steel. CORSA’s Xtreme design combines a straight-through, non-restrictive exhaust path with its patented reflective sound-cancellation technology, intended to reduce the low-frequency sound associated with cabin drone while delivering a crisp exhaust note.
The system’s design is intended to reduce backpressure and support engine horsepower and torque. It includes two chambered 304 stainless steel mufflers, each with a single inlet and single outlet, plus polished stainless steel tips.
