EXHAUSTS

You may be weighing up the choice between a standard exhaust and a performance exhaust. Every aftermarket exhaust I've seen from a motor factor are made using pressure bends - these severely restrict gasflow and will cost you a chunk of horsepower not to mention raising combustion temperatures. So your choice is simple - Original exhaust from a dealer or an aftermarket performance system which are mandrel bent not pressure bent. 


Car Exhaust systems can be replaced to liberate more Horsepower. Changing an exhaust system for a Milltek or Supersprint one one with less back pressure can produce more power. This is especially the case on a turbo engined car which like two stroke bikes, live and die by the exhaust. There is always noise to consider, not just for the road but at circuits to. Many circuits have quite stringent noise tests in place. You will not want a single box race system for a trackday at Goodwood for instance.

There are many different exhausts on the market. In fact the choice is bewildering. In keeping with our philosophy of ensuring that each part we sell offers definite performance improvements we will not sell exhausts where the manufacturer is not confident in their ability to increase horsepower. Bolting on massive diameter tubing and huge tailpipes can possibly even lose horsepower (except perhaps on a turbo where this seems to be the norm) because the exhaust gases lose temperature and hence reduce in speed. The system itself is actually not as important in generating power as the manifold. The exhaust manifold on a standard car is a design compromise. Usually cast iron, they often flow well but when you start upgrading, especially with a high performance camshaft, they become a weak link in the chain. The tubular manifold not only looks the part it is designed to “extract” the waste gases through pulse tuning. There is a lot of science behind this. It is to do with gas dynamics and a cleverly designed manifold will give a good increase in power as standard and enable a performance camshaft to really reach it's potential. By extracting the waste gases there is more room for fresh air and fuel resulting in more efficient combusition. This can give more torque and hence more power.

Changing an exhaust system for one with less back pressure can produce more horsepower. This is especially the case on a turbo engined car which like two stroke bikes, live and die by the exhaust. Another engine that lives and dies by the exhaust is one with a lot of valve lift at TDC (or Overlap) There is always noise to consider, not just for the road but at circuits to.
