Similar design to the works manifolds, the front left hand outrigger cut-out must be to the BJ8 size. The twin carb manifold will make the single most increase in power and torque possible for the money spent. Very high quality mild steel with mandrill formed bends to keep a constant tube size. These will last for many years and have the added advantages over Stainless Steel of reduced noise and fatigue cracking. The twin SU manifold will require a small relieving of the inlet manifold, as per the instructions provided with the manifold. Finished with Black heatproof paint.

Suitable for twin and triple SU carbs.

All our exhaust systems are manufactured to the highest tolerences and specifications 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 the systems.  They do not suffer with reduced pipe diameter on the bends as most of our competitiors 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 damange and ensure an improved fit.
