Decat downpipes will increase flow over the stock units and reduce back-pressure, therefore allowing greater power and torque output, especially if you are tuning the vehicle.

These downpipes are direct fit, and are a direct bolt on, minimal tools are required if fitting DIY, or we can install in house, please contact us for a quote.

Will also fit to many aftermarket cat-back systems, please contact us if you are unsure.

De-cat downpipes are for off-road use only. Fitment of a decat downpipe to your vehicle may bring an EML on the dash unless re-mapped or coded out. This item will not pass a UK MOT or police check.
