Borla 18-19 Jeep Grand Cherokee Trackhawk S-Type Muffler Kit - 3in Pipe Diameter

If you've got a Borla Cat-Back system on your 2018-2021 Jeep Grand Cherokee Trackhawk and want to dial in the exhaust note, this S-Type muffler kit is what you're looking for. It's designed to swap out the more aggressive ATAK sound level for the slightly more mellow, but still sporty, S-Type tone. This isn't a standalone muffler; it's specifically made to integrate with Borla's 140756 Cat-Back system, so you know it'll connect properly.

Borla builds these mufflers from T-304 stainless steel, which is a strong material that holds up well against corrosion, especially compared to lower grades like T-400 series. The internal design features ultra-smooth, mandrel-bent pipes. This process bends the tubing without crushing it, ensuring the exhaust gases can flow as freely as possible, which helps with both sound and performance. Precision manufacturing means it fits right into your existing Borla setup.

Because this is designed to work exclusively with Borla Cat-Back systems, you can expect a direct fit installation. Borla backs this muffler with a Million-Mile Warranty, showing their confidence in the durability and build quality of their exhaust components.
