EXHAUST AND FUEL SYSTEMS

There are two main types of exhaust system: a modified road system or a two-intoone system. A basic rule of thumb is that the standard system gives better torque and is easy to fit onto existing mountings, while the two-into-one gives better top-end power.

Most race cars use a non-standard exhaust – anything goes, and several suppliers can make one to order. Normally they exit in front of the nearside rear wheel.

The fuel system is pretty much standard. The tank must have a roll-over one-way breather fitted. Check the fuel pipe and upgrade it with ethanolresistant tubing.
