Adding headers and removing catalytic converters from the exhaust is one of the top things to do to make more power. The factory put the cats in the stock exhaust manifold which restricts exhaust flow. But any race or track car will want to run without cats to gain the most power and torque. We used these on our in-house 325i project car on our way to 272hp. These Supersprint stainless headers are a true tubular, equal length design that bolt up for an immediate power gain. With no cats and a race exhaust you can expect to gain 15-20hp over the stock exhaust setup. Power gains with a cat section depend on the type of cat.
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 design because every aspect is done to such a high level. 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 You have a few different options for the exhaust immediately after the headers (known as 'section 1'):
Stock Section 1 Cats*Sport Cats*Straight Pipes**
* - you will need to have the rear O2 sensors extended to the new location of the cats. Special software or stand-alone engine management may be required to prevent fault codes and other conditions. ** - any cat-less section is sold expressly for race or on-track use only. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.
