Built as a direct OEM replacement, JHM Downpipes are easy to install with simple hand tools with no cutting or welding required. These downpipes are designed to increase low-end torque and maximize power throughout the entire RPM band. By moving the catalytic converters further downstream into the downpipes, JHM was able to take full advantage of their own 2.5" Race Pipes to alleviate heat build-up close to the engine. As a result, this increases Catalytic Converter longevity, as well as overall engine performance.
Please note: These downpipes do not replace, but instead relocate the factory catalytic converter sections that are directly connected to the exhaust manifolds. Instead, these downpipes connect to the factory catalytic converter section. Please see the illustration in the images above for more information. If you have any questions, please contact us before placing an order for these downpipes.
You will need to either purchase a set of JHM Race Pipes (see links above for pipes that are applicable to your model) or modify your existing factory downpipes in order to properly install these downpipes.
