We work with stainless steel for all types or car - standard, race cars, rally cars, performance cars and prestige vehicle. We also work with two types of bending methods. Type one is the standard pipe bends which come in all standard everyday road car exhausts from factory, and type two is weld in mandrel bends which gives the best free flowing exhaust system available on the market. Mandrel bends are the highest quality bend you can get. We fit this type on all race cars/performance/rally cars/drift cars/high performance if required.

There is a lot more time put into a stainless steel mandrel bent exhaust system so this is the more expensive option.

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.
