Supersprint offers a performance, full exhaust system, including a Turbo downpipe kit, for the F12/F13 2012->2018 Alpina B6 Coupè / Cabrio and for the 2014 F06 Alpina B6 Grancoupè x-Drive, with the 540 Hp/ 600 Hp, Twin Turbo N63N V8 engine.
This Supersprint exhaust also fits the exclusive "Bi-Turbo Edition 50" model.
Built with 70mm oversize diameter tubing, this Supersprint exhaust is the best addition to the Alpina B6, making substantial Hp and torque gains, and adding a great sound at the same time.
The Supersprint full system is designed to complement the huge potential of this Alpina / BMW engine.
When matched with a ECU reprogramming, the flowing capacity of this Supersprint exhaust is 700 + Hp.
The Turbo Downpipes are made with a set of integrated, built-in HJS Motorsport, 100 cpsi 130mm catalytics (made in Germany), the largest-volume, best flowing performance cats in business.
With this proprietary exhaust design, Supersprint eliminates the power-robbing bottlenecks in the exhaust system, made by overly restrictive, oem cats.
By freeing up this exhaust tract, the efficiency of the twin turbochargers improves by a massive amount, and the temperature in the engine exhaust port area gets considerably lower.
This in turn helps the boost pressure to remain more constant under heavy use, while the emissions are mantained under control at the same time.
These same Supersprint Downpipes also accept the stock exhaust, bolting up directly to the Alpina Factory cat-back system, and they are available in a Racing, cat-deleting version, as well.
