S550 GT Stage 3 NA

NOTE: Fancy a supercharger or Turbo? Be sure to let us know. Depending on your long term goals we will make different suggestions for this stage. 

Assuming you have already completed stage 1 and 2 or even just 1, the next step after freeing up your engines intake is to free up the exhaust.

To achieve this you will need to rid it of the EU specification exhaust manifolds and the factory catalytic converters, then replace them with CAD designed long runner headers. You can choose to either do away with the cats completely (off road use only) or opt for high flow cats and remain MOT compliant.

We haven't yet found a better designed, built or put together set of manifolds for the S550 GT than KOOKS and as such fit them wherever possible as part of our Stage 3 Power Package.

To make the most of this do you already have a full catback system on your car?
