Standard bore LCB exhaust manifold, excellent all round header for almost all road applications including well tuned fast road 1275s. Exit pipe dimensions of 1.625"od and the center downpipe is 1.5" od. 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 have 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. Our "Maniflow" manufactured headers are the most cost effective high performance headers available today! 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 Maniflow 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. See C-AHT12 for exhaust pipe "system". See C-AHT11/LCB/BIGBORE for large bore LCB. Available as C-AHT11-LCB-BIG , C-AHT11, AND C-AHT11-3-1 .

Medium LCB header manifold and single box exhaust system in 1.625" (1 5/8") size for Sprites and Midgets with 1275cc engines.
There are a very limited number of exhaust systems that actually produce more power, yet maintain a civilized noise level.
This exhaust system is designed and manufactured by Maniflow in the UK. This makes installation an easy bolt-on operation that fits right the first time.

The Long Center Branch exhaust manifold design has long been recognized as the best option for high performance. Our "Big Bore" special makes it a must for all serious performance hungry drivers. The big bore designation does not imply engine application but rather the 2" diameter of the manifold pipe outlet!
Maniflow's LCB exhaust header is ideally suited for Spridgets with very hot street to full race 1275s with cams of up to 300 degree duration. It is well suited for autocross, and vintage race applications. It has 1.65" center downpipes and 2"id outlet at the collector.
