Since our inception we've worked on everything from standard road cars, through limosines to Ariel Atoms. Some of the biggest magazines in the industry have chosen us to build their show exhausts and you'll see examples in Fast Car, Max Power, Redline and Total Vauxhall to name but a few. We have a friendly team who'll give you expert advice so drop in for a chat and see what we're able to do for you.

Custom Build Exhaust Process


ECU Remapping by Topgear Tuning

ECU programming will improve power and torque figures, increase throttle response and widen the power-band, resulting in a more flexible engine and a much sharper drive.

Another major benefit of remapping is a reduction in fuel consumption. Extra torque at the bottom of the rev range requires less throttle input on acceleration and when maintaining steady speeds. The vehicle can also be driven in a higher gear at slower speeds, thus reducing revs, and this also applies to driving when fully loaded, towing or driving through elevation changes.
