Frequently Asked Questions
What is the COR14992?The COR14992 is a Corsa Performance Sport cat-back exhaust system designed for the 2014-2021 Jeep Grand Cherokee Summit 5.7L HEMI V8. It uses patented RSC Technology to deliver an aggressive HEMI tone while eliminating interior drone, and features polished 4.0-inch Pro-Series tips for a premium appearance.
Will the COR14992 fit my Jeep Grand Cherokee Summit with the 5.7L HEMI?Yes. The COR14992 is specifically designed for 2014-2021 Jeep Grand Cherokee Summit models equipped with the 5.7L HEMI V8. It is not compatible with SRT 6.4L or Trackhawk 6.2L engines.
