Product Details

Special pricing! Free ground shipping! These Supersprint 'Partial-Stepped' headers for the US E46 M3 are a replacement for the stock manifolds/cats and an upgrade from the standard Supersprint headers. This header is a partially stepped design - the tubing diameter increases as it leaves the exhaust port, which helps exhaust flow, but has the factory-sized outlet so it can connect to a factory section 1 exhaust. For making E46 M3 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears).

Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and de-forming (any headers not made from stainless suffer from structural problems). Supersprint designs their headers with CAD programs and 50 years of exhaust tuning experience. These headers are an improvement over any 'Euro style' header on the market. This part is designed for the US market with the correct flanges for the US exhaust and the O2 and EGT sensor ports pre-installed. Special software or stand alone engine management would be required to keep check engine and fault codes from appearing. Software is recommended to maximize the performance gains from this header upgrade.

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!

Section 1 / Catalytic Converter Options
With this Supersprint part number, there are no options for the exhaust immediately after the headers (known as 'section 1'). It only works with the stock US section 1 or similar.
