BMW Performance Headers & Downpipes for BMW E21 320i M10 1.8L

Headers should be part of any M20 performance project or restoration. These Supersprint tubular headers are a larger diameter and have better flow than the stock cast iron exhaust manifolds and they make more power. And since the stock headers are known to be brittle and can crack over time these make for an excellent upgrade replacement.

This header system mimics the stock exhaust after the header collectors. It uses the same 3-bolt flange as the original 323 center resonator. This makes them a direct swap from the stock manifolds and downpipes and an easy fitment for a 323 with the stock exhaust. Supersprint also makes a center resonator section and rear mufflers to build a complete system.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!
