Spider Racing Exhaust Manifold

This is a racing 4-2-1 exhaust manifold suitable and essential to make maximum power with engines using high lift, long duration camshafts and individual throttle body fuel injection.  Also suitable for use on standard engines and still gives good gains over the standard manifold.

The manifold features:

Primary and secondary pipe sizes and lengths designed by top engine consultant Sandy Brown,

Stepped exhaust flange to reduce exhaust reversion back into the exhaust ports,

Separate primary and secondary pipes held together with retaining springs.

Slip on, TIG welded, handmade merge collectors.

Full 304 stainless steel construction, back purged and TIG welded so that the inside of the welds are smooth, improving gas flow.  These systems are designed by us and are made by a UK supercar exhaust manufacturer exclusively for us.

Gives a very good increase in midrange torque (up nearly 15lbft at 4250rpm) and power is up everywhere.

 
This manifold can be fitted with our racing exhaust systems.

Please note these systems are not held in stock all of the time so please allow 8 weeks for delivery.
