This 2.75" diameter High Clearance Climber / Rock Crawler Cat-Back 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. Positioned between the Touring and the ATAK®, 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. This system is specifically tuned for flow and sound on the Bronco's 2.7L engine. 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®. 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.
