Standard exhausts are made of mild steel.These gradually corrode (rust) from the inside and the outside. Rust is formed when iron corrodes in the presence of oxygen and water. Hot gases (produced from the combustion process of burning fuel in the engine) are expelled through the pipe. When the engine stops and begins to cool, condensation forms on the cooling surfaces, encouraging the rusting process.
A car exhaust is naturally close to whatever road surface the vehicle is running on. Driving on wet surfaces, travelling in bad weather, running over salted roads in Winter, all contribute to the rusting process of mild steel.
Cars used for short journeys tend to find their mild steel exhausts corroding much quicker than those used for longer distances. The water vapour created by the internal combustion of the engine doesn’t heat up enough to evaporate. Instead, it becomes trapped in the silencer. As described above, the mixture of oxygen and water causes corrosion and rots both the silencer and its connecting pipes from both the outside in and the inside out. With a Stainless Steel exhaust, this will never happen, due to its chromium content.
All our welding is done this way, which gives a stronger,more penetrative weld, is splat free, and has a much smoother, neater finish than Mig welding.
The combination of T304 & T316 Stainless Steel and High Frequency Tig welding means we can give all our systems a lifetime guarantee. It also means no corrosion therefore your power and performance remains the same from the day it was designed and fitted, throughout the life of your vehicle.
