We have been selling the Gruppe M product for many years and they have recently restructured some of their pricing. Made of the highest quality carbon fiber, GruppeM's exclusive ram-air design cools the intake charge from excess engine heat and forces a higher volume of air into the engine's manifold for more power and a throaty sound. They have a system available for the TT-S and TT-RS and its been some of the best carbon fiber we have seen. There are a lot of good systems on the market and this is another option for carbon lovers.
