Frequently Asked Questions
What is the COR14991?The Corsa COR14991 is a Sport-level 2.5-inch cat-back exhaust for the 2011-2021 Jeep Grand Cherokee 5.7L HEMI V8, delivering an enhanced HEMI exhaust note with Corsa's RSC drone-free technology and a 4.5-inch polished tip.
Does the COR14991 fit the 6.4L SRT Grand Cherokee?No. The COR14991 is engineered for the 5.7L HEMI. For the 6.4L SRT, see Corsa's COR21058 series.
Will the COR14991 drone on long highway drives?No. RSC technology actively cancels the standing waves that cause drone, so the COR14991 is quiet at cruise RPM and louder at acceleration and full throttle.
