Billy Boat's S4 Exhaust is a stainless steel mandrel bent cat-back exhaust. Our exhaust begins after the two lower factory catalytic converters and is two 2.25" pipes that merge into one 3" pipe. This exhaust is very quiet and simply changes the tone of the exhaust to a deep unobtrusive sound. With TIG welding fully stainless construction and CNC'd hangers you will not find a higher quality system on the market.
This stealth system is quieter, and helps cut down on the noise that some enthusiasts hate.
