A hand ported and flowed set of V6 duratec heads will cost $1400.00 The customer will recieve before and after flow numbers on there actual set of heads. Give us a call for more details.

Nautilus Performance Group will soon start offering a performance throttle body package for the Rossion/Noble that includes a spacer and throttle body. In case you are wondering what a Throttle body actually is, it is the part of the air intake system that controls the amount of air that flows into an engine's combustion chamber. With a performance Throttle body you are increasing the air that can flow into the engine's combustion chamber. This results in a more powerful burn that leads to an increase in horsepower. 

What are you waiting for? Come and take a look at this hand-built 2008 BMW 135i I6 twin turbo exhaust system we have recently finished building for one of our customers. Nautilus Performance Group takes a lot of pride in creating custom performance components for cars, and if you are looking to have something fabricated for you car please don't hesitate to contact us.
