Exhaust Manifolds

Set of three stainless steel band clamps to fit big-bore LCBs. These clamps tighten down better that the ones supplied with the header, and are thinner.

Set of three stainless steel band clamps to fit standard bore LCBs. These clamps tighten down better that the ones supplied with the header, and are thinner.

Exhaust manifold to downpipe clamp. The key to eliminating exhaust leaks at the manifold flange is the clamp. These new clamps include proper brass nuts and support washers

This is the welded steel tubular header that replaces the original 12G615 pressed steel version used on Cooper and Cooper S models. Ideal for 998-1098cc engines and stock-built 1275cc classic Minis.

Fits original cast iron exhaust downpipe on SPi and MPi (fuel-injected) classic Mini models. Special all-metal self-locking nut in metric thread

This universal bung can be welded into your exhaust system to allow the mounting of an Oxygen Sensor for real-time engine combustion readings.

This down pipe connects to a standard one-piece single-outlet cast iron manifold and will allow you to upgrade to the larger bore RC40 or similar exhaust system

This bracket should be used to reduce the tendancy of the exhaust header to crack. It bolts to the transmission side cover and connects to the bottom of the

Mild steel bracket that attaches to gearbox bolts to steady exhaust manifold and prevent excess movement that can crack the manifold
