Standard bore LCB, excellent all round for almost all road applications including well tuned fast road 1275s. Exit pipe dimensions of 1.625"od and 1.5"id.
General:
Many years of research and development have been spent on what on the surface is only a necessary evil! Getting the exhaust out of the engine would seem simple enough but modern technology and manufacturing has made it a real science. The LCB (Long Center Branch) header (exhaust manifold) has been developed to the point that an actual improvement in performance can be achieved by its use.
They not only fit well and add performance but also are long lasting!
Ease of fitting and high production quality combined with maximum flow for power make the exhaust manifolds (tubular steel headers) an unbeatable value. Special attention is paid to all joints and welds to obtain required backpressure and exhaust gas flow.
