These are a bigger bore than the original 100M and on a full race or rally engine will give more power.

The silencer is very large and therefore lasts a good length of time, with the choice of trouser it can be set up for the big bore or 100M manifold.

The trouser and tail pipe must be welded to the silencer to suit the car and therefore are unpainted.

The front and rear outrigger must be modified and please note the manifold does not accept the original throttle linkage, it is recommended to convert to cable throttle.

All our exhaust systems are manufactured to the highest tolerances and specification, and are made of top quality thick mild steel.  We have done this to eliminate the resonance caused when using stainless steel, therefore helping to keep the noise to a tolerable level.

They are supplied with heat proof black paint on the manifolds and gloss black flame proof paint on he systems.  They do not suffer with reduced pipe diameter on the bends as most of our competitors do.

Now pressure tested for even better quality, as small imperfections in the welds can create an air leak, which is the cause of annoying popping on over run.  Also now supplied with support straps across the flanges to prevent any transport damage and ensure an improved fit to the head.
