For the VX 220 supercharged cars it’s difficult to state one exact system and price. The power levels vary so considerably that this system is partially custom made so it would be best to call and discuss the specification you require. The system will be based on a the new profile silencer with straight-thru baffle, 3” bore a optional  2” 4-1 manifold (a must for powers +300bhp SC installs) A silenced De-cat will be needed for powers +350/400bhp. These systems sound fantastic and at MMG we have a range of custom base maps ready to get the best from the car.
