This 2.75" diameter High Clearance Climber / Rock Crawler Cat-Back(tm) system is designed with ground clearance in mind. It features a brushed 2.75" T-304 stainless steel turn down tip and is the ideal system for off-roading, overlanding, or rock crawling. This system is specifically tuned for flow and sound on the Bronco's 2.3L engine. Positioned between the Touring and the ATAK(r), the S-Type delivers a noticeable increase in sound and overall volume without being intrusive. As expected, the system is drone-free to ensure an enjoyable ride inside the vehicle. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. The system's T-304 stainless steel construction ensures it can handle whatever you throw its way. For performance and sound on the trails, choose Borla(r). Best of all, we stand behind every system with a Million-Mile Warranty, just what you'd expect from the world's most experienced (and most winning) exhaust brand.
