The exhaust system of your car plays a vital part in your cars performance by allowing toxic particles to leave the engine of your vehicle and out via steel tubes. This helps keep the driver of the car safe and ensure good fuel economy by ensuring efficient conditions for the vehicle to work in.
A custom built exhaust means that a bespoke designed and fully fabricated system is built and fitted to your vehicle to replace your existing system to improve your vehicles appearance and/or performance.
Most exhaust systems fitted to cars in the uk are made from mild steel leaving them open to corrosion. In a damp country like Scotland this can be quite common in a lot of vehicles. Also the gases released from combustion can be damp also have result in moisture build up leading to corrosion-the enemy of every vehicle owner
Exhaust are often put on as an afterthought by the manufacturer with no attention paid to their impact on the vehicles long term durability as the extra cost of stainless steel puts many manufacturers off stainless steel.
