Standard bore Budget priced LCB (1-3/4"id) with pre cast flanges to improve flow and save engine tuners time matching the ports. This is ideal for very hot small bore engines and for standard to high performance 1275s, including road 1380s.
There is NOT enough clearance room when fitting to old cars with rubber couplings which foul. Using
QL5000 type couplings will help but re-shaping of manifold is still required in most cases. The Long Centre Branch design has been proven to be the best all-round for our 5 port cylinder heads. Bore diameter being the only other variable. Has 2 Y piece to LCB fixing clamps plus the Y piece to exhaust down pipe clamp.
