BMW E24 633 CSi (M30) '75 -> '81

The 1975-1981 BMW 633 CSi is a legendary sportcoupè, which has become one of the most sought after models in recent times.

Supersprint still builds the tubular stainless headers and exhaust to make the performance substantially stronger and the sound to become perfect at the same time.

Our original projects and blueprints are 45+ year old, yet they are very up to date.

The Supersprint proprietary exhaust design made this system a winner back then, and it still can be considered modern by today standards.

No less important, we guarantee a perfect routing of the pipes, with the proper, safe clearance throughout the engine bay and underneath the chassis, a spot-on fitment on the stock hanger provisions and an unequalled durability.

All of the flanges are precision machined, and the swaged coupling ends of the piping connections are matched exactly to the BMW oem specs, accepting the stock gaskets and sealing rings, with no modification required for the install.
On a final note, the endpipes have a perfect placement of the exit tips, and are available in distinct versions for the Euro and for the US rear bumper.

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. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
