BORLA® is proud to present their exhaust systems for the Ford Explorer ST, Explorer Platimun, and Lincoln Aviator. Our Cat-Back systems have been specifically developed for the 3.0L V6 EcoBoost engine with performance and sound in mind. The S-Type Cat-Back system delivers a balanced, sporty sound without adding any drone inside the vehicle to ensure an enjoyable driving experience. The front muffler contains an internal H-Pipe for increased performance and improved sound. This system features black chrome on T-304 stainless steel tips, but is also available with bright chrome on T-304 stainless steel or carbon fiber tips. Using BORLA® Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. Our exhaust is constructed using premium T-304 stainless steel and bolts on to the factory system for stress-free installation.
