Our stainless turbo downpipe uses a large volume, 130mm HJS Motorsport 100 cpsi cat, for minimum resistence, and superior hp and torque gains.
It guarantees a massive improvement in exhaust gas flow, when compared to the stock catalytic.
When it comes to performance, Supersprint has a completely different approach to the problem area, totally opposite to the other muffler-only options available on the market today.
Our 80mm entire exhaust has a perfectly round section, all the way to the rear muffler; it is not crushed down in the places where clearance is critical, thanks to the careful, precise routing of the pipes.
This full system has a huge flowing capacity, which makes it the ideal complement to any engine tune up to 400+ Hp.
The Supersprint dual-sound mode rear mufflers use a built in-house, precision machined flap, operated by the same electric servomotor of the stock system.
This ensures an easy, trouble free installation, and a long life.
It guarantees a deep, sporty tone, with no droning when closed, and a wild, race-like scream when open.
We offer a dual tip version, for the std M Sport diffuser, and a quad-tip option as well, for modified bumpers.
