BMW E21/E30 4-2-1 manifold (1,8/2,0 4-cyl) LHD

Martelius Exhausts are made in Finland for Left hand drive cars so may not fit Right hand drive vehicles. If your car has the steering column on the intake side of the engine then the exhaust manifold should fit no problem. If your steering column is on the exhaust side of the engine then the Exhaust manifold will probably not fit and may require modification to clear the steering column. 

Delivery time 8 weeks from order.

For the M10-type engine (chain-driven camshafts). Pipe diameters (mm) 44.5-> 44.5-> 50.8. Mild steel with thermal isolating TechLine BlackSatin ceramic coating. Designed for max. 170hp. Provides very wide power range.

Collector part is fitted with springs. That eliminates the risk of primary pipe cracking due to engine movement. Also that makes it possible to tune power range. Shortening of seconary pipes will move power range to higher revs.
