Supersprint is proud to offer the first, real-world performance exhaust for the limited edition, 2018 BMW M5 F90 Competition.
Our R&D team started out by evaluating that the oem manifold and the dual-stage downpipe/catalytic assembly put a serious limitation to the performance potential of this 625 Hp powerplant, the incredibly solid S63M, Twin Turbo V8 engine.
This is the area of the exhaust where we have focused our attention, exclusively.
We have found out that the remaining section of the std exhaust, the cat-back part, does not cause any loss, as it proved to be an excellent, perfectly efficient dual-branch design.
Technically speaking, it is a free flowing unit, built with the proper size, 80mm pipe diameter.
Once the flaps go into the open mode, there is no restriction to the exhaust gas built up within the single box muffler.
As is, the std cat-back system leaves no room for improvement in the exhaust dynamics' overall picture.
The F90 M5 Competition really needs a headers and a turbo downpipe kit, to release its full potential.
The new, M xdrive 4x4 system is the perfect platform for 800+ hp engine tunes, putting each single hp to the ground.
We at Supersprint have developed a specific exhaust kit to complement and enhance these gains even further.
Enter our new Tubular Headers and R&L Turbo Downpipes, which totally eliminate the restrictions found in the front section of the exhaust system.
The new Supersprint headers use the same pattern as the stock exhaust manifold, which merges the primaries in pairs, from opposite side cilynders (based upon the specific firing pattern of the individual 8 cylinders). This feature makes the most advantage of the exhaust gas charge into each one of the D-shaped inlet ports of the twin scroll turbos.
Furthermore, the Supersprint full tubular design of the eight cilynder primaries 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 turbo efficiency by a great amount, transforming the faster spooling into energy for a massive increase in boost pressure of the intake air charge, at all rpm.
The steel alloy for the tubing of the Supersprint headers is the 310S, which had been developed specifically years ago by the metal industry, and rose to fame on F1 and other premier race headers applications.
The thermal stablity of the special alloy, and the design of the Supersprint's own expansion joints / sealing rings ensure a leak-free operation, an optimum resistence to the extreme temperature of the exhaust gas, 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 cats, with the lowest 100 cpsi density, this Supersprint exhaust system translates into 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, for milder tunes, in conjunction with the stock manifolds.
They allow the engine to work at lower operating temperatures, over a longer period, reducing heat soak drastically.
Installation is a direct, bolt-on job. No modifications required.
