When it comes to performance, Supersprint has a totally different approach to the problem area; we always develope unique exhausts, nothing like any other option available on the market today.
Our stainless turbo downpipe uses a large volume, 130mm HJS Motorsport 100 cpsi cat, for minimum resistence, and superior hp and torque gains.
It is also available in a 200 cpsi, and in a race-only, cat-deleting version.
These Supersprint turbo downpipes guarantee a massive improvement in exhaust gas flow to the B58 3.0L Twin scroll Turbo engine, in comparison to the restrictive, stock catalytic, becoming the ideal complement to 400 + Hp engine tunes.
Our 80mm exhaust has a perfectly round section, from front all the way to the rear muffler; it is not crushed down and flattened to a smaller cross section, in the places where clearance is most critical.
On the Supersprint system we carefully route the tubing to obtain the most perfect layout, providing for the proper, safe distance from the chassis and from the ground, at the same time.
The Supersprint dual-sound rear muffler uses a precision machined, built in house, stainless flap, operated by the same electric servomotor of the stock system.
This guarantees an easy, trouble free installation, a perfect switching operation and a long life.
We offer a dual tip version, for the std and for the M Sport diffuser, and a quad-tip option as well, for the conversion to the M4 style bumper.
