Supersprint has finally delivered the first batch of its stainless headers for the new BMW M5 V10. They are currently available through Hamann Motorsport. The increase in performance is outstanding, and it exceeds the gains made on the older E39 M5 V8.The entire development process took place in 2005.
It took several months to design, hand built prototypes, dyno-test and then handcraft these headers in their current form.
Supersprint also has patented the design of these headers, as well as several of their individual, technical features, which are vital to the function, the performance, the fitting and the durability. The primary pipes of the Supersprint headers are oversize in diameter, when compared to stock, and their round cross-section remains constant from the cylinder head ports, all the way to the 5-1 right & left collectors.
On the contrary, the stock headers use primary pipes, which are highly deformed in several areas, where their section reduces down and shrinks dramatically. This causes a loss of efficiency, in terms of flow-rate and performance. The design of the stock headers is vastly improved, when compared to the older E39 M5 stock headers, however it is still far from perfect, and has several serious flaws.
Supersprint managed to design a genuine race exhaust headers, and squeeze it into the extremely cramped space available inside of the engine bay. It took an effort of epic proportions to achieve this, in terms of designing and hand building prototypes, but the Supersprint team still made its goal, brilliantly.

The Supersprint headers do not use pre-cats at all, but rather merge its individual primaries into F1 collectors, and connect them directly to the main cats, thus eliminating one of the main sources of restriction in the entire exhaust system.
The installation of the Supersprint headers to the stock cats is a simple bolt-on job, no welding in involved. As an option, Supersprint also offers a set of special, hi-volume metallic cats, which further enhance the performance.
These cats use Emitec-HJS Motorsport monoliths, 100cpsi, and they are totally OBD II compatible. O2 sensor ports are present on the headers, and also down streams of the cats. This means that the CEL is not triggered at any time.
Their volume, as well as the shape, size and taper of the connecting
pipes are all specifically designed for the BMW V10 engine.
The most notable feature about the fitting is that the engine remains in place. A few, easy steps must be followed when removing the stock headers system, however the engine remains untouched. This dramatically reduces the installation costs and the downtime.
Wow! What is the hp on the dyno with full Supersprint exhaust system including headers & backboxes fitted??
How much does it cost? M5board discount?

looks awesome with the pipes smoothe flowing from the headers to the cats, compared to the squeezed snaking pipes of OEM. Will be interesting to see the HP gains and price. Thanks for the heads up, a great report.

Hey guys, make sure , before you ask how much, you look Very carefully at dyno specs and if any parts need relocation or modification FIRST. True you dont have to unbolt engine mounts,,,But the installation DOESN'T end there
