Billy Boat's turbo-back exhaust is a stainless steel mandrel bent system. Our turbo-back exhaust begins at the downpipe which leads to a catalytic converter then to a 2.5" center pipe which contains a small 4" resonator. The 2.5" pipe continues back to the polished muffler and then to the polished tip or tips depending on your vehicle. With TIG welding fully stainless construction and CNC'd hangers you will not find a higher quality system on the market.

California residents are advised to check local laws regarding aftermarket catalytic converters.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
