Description

The CORSA Performance Jeep Wrangler JKU catback exhaust system features CORSA's Patented Reflective Sound Cancellation(R) (RSC) Technology allows acoustic engineers to create an aggressive drone free exhaust note, styled specifically to fit the personality of your vehicle. This catback exhaust system moves the muffler to the center of the vehicle providing for better clearance and maximum approach angles for offroad driving. CORSA's full catback exhaust allowed our acoustic engineers to get added deep tonality from the V6 engine creating and AGGRESSIVE V8 LIKE SOUND under acceleration while maintaininig a DRONE-FREE EXPERIENCE during cruise. Choose from 4 unique tip options: Dump-style for maximum offroad clearance, polished, black or our American Flag option. Performance gains are not affected by sound choice.
