Borla Performance S-Type Muffler Upgrade Kit - 2015-2021 Grand Cherokee SRT 6.4L V8 (60634)
Tune the aggressive growl of your high-performance SUV with the Borla Performance S-Type Muffler Upgrade Kit for the 2015-2021 Jeep Grand Cherokee SRT WK2 6.4L V8. This premium modular sound-changing solution is specifically engineered for track enthusiasts who want to change their current acoustic profile. Developed as a direct-fit acoustic swap, this kit allows owners to convert an ultra-aggressive Borla ATAK cat-back system (part numbers 140633 or 140633CB) into a slightly more refined, deeper S-Type sound signature. It delivers a rich, muscle-car rumble under acceleration while maintaining optimal comfort inside the cabin during daily driving or highway cruising.
Built to withstand extreme exhaust gas temperatures and harsh performance conditions, this modular upgrade kit is manufactured from high-quality T-304 austenitic stainless steel, outlasting low-grade T-400 series alternatives. Precision computer numerical control (CNC) manufacturing processes ensure accurate alignment underneath the vehicle, while ultra-smooth mandrel bends preserve maximum exhaust gas velocity. Featuring an optimized heavy-duty structural layout, this conversion kit integrates effortlessly into your existing Borla infrastructure. This product is proudly made in the USA and is backed by Borla's legendary lifetime Million-Mile Warranty.
