BMW F91 M8 Cabrio / Convertible M X-Drive 4.4i V8 (S63M - 600 Hp - models with OPF) 2020 ->

Supersprint is proud to offer the first, real-world performance exhaust for the newer, most prestigious BMW Motorsport car, the 2020 BMW M8 Cabrio / Convertible.

Our R&D team started out by evaluating that the oem manifold and the dual-stage downpipe/catalytic assembly + OPF / particle filter system puts a serious limitation to the performance potential of this 600 Hp magnificent powerplant, the incredibly solid 4.4L Twin Turbo V8 S63 engine.

This is the most critical area of the exhaust, by far.

Our new Tubular Headers and R&L Turbo Downpipes totally eliminate the restrictions, supporting even the most radical conversions to 800+ Hp.

The new Supersprint headers use the same exhaust path scheme as the stock exhaust manifold, which merges the primaries in pairs, from opposite-side cilynders (based upon the specific firing pattern of the eight individual cylinders).
This feature makes the most advantage of the exhaust gas charge, when entering the D-shaped inlet ports of the twin scroll turbos.

However, the Supersprint , full tubular design of the indivudual primary runners eliminates all of the necked down, compromised sections of the undersized stock manifolds,while the precision crafted, merge collectors reduce the thermal losses.
This in turn improves the turbochargers' efficiency by a great amount, transforming the faster spooling into additional energy, for a massive increase in boost pressure of the intake air, at all rpm.

The grade of the tubing for the Supersprint headers is the 310S, a special steel alloy which had been developed specifically by the metal industry for high performance-focused applications, rising to fame on F1 and other premier race headers builds.

The thermal stablity of this unique material, and the design of the Supersprint's own expansion joints / sealing rings ensure a leak-free operation, under the most the extreme temperature and operating conditions, and a service-free, long life of the headers.

When mated to the Supersprint free-flowing Turbo Downpipes, which use a set of high volume, 130mm HJS Motorsport R&L cats, with the lowest 100 cpsi density rate, this Supersprint exhaust system guarantees a much stronger torque at low and mid rpm, as well as substantially more hp at peak.

The Supersprint R&L Downpipes can also be used as a Stage 1 exhaust upgrade, in conjunction with the stock manifolds, complementing tuning steps.

They allow the engine to work at lower operating temperatures, reducing heat soak drastically, ensuring more consistent performance.

Installation is a direct, bolt-on job. No modifications required.

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.
