BMW E90 Sedan M3 4.0 V8 '07 -> '11 Supercharger conversion

Supersprint is proud to introduce its long tube, oversize stainless headers system for the BMW E92 M3 Coupè. It also applies to the E90 sedan, to the E93 convertible, and to the M3 GTS.

This performance headers is designed to enhance the flow on the conversion of the S65 engine to supercharging, which is becoming more popular every day among the M3 enthusiasts.

While the oem BMW Factory headers is extremely well designed, and it offers a perfect blend of torque and max hp on the stock engine, it lacks flow and becomes overly restrictive when used in conjunction with supercharging.

The SS new headers is designed to do exactly this, guaranteeing the perfect flow rate for a radical modification, up to 700-750 hp.

Large tubing diameter, an equal-lenght primary design, and race-spec, 4-into-1 collectors are the main features of the new Supersprint S65 headers.

As usual with all of the Supersprint performance headers and exhausts, the installation is an easy, straightfoward process, the fitment is spot on, and the durability is second to none.

We recommend using this SS headers system on S/C conversions only, not on stock S65 engines.

Systems for replacement of kat for OBD II car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur.
