Hand crafted in Canada, our 88mm Cat Back Exhaust has been designed with a pressure relief valve making it the best choice for both turbo charged and NA applications. HPA's custom noise silencing mufflers manage the drone while the exhaust flapper opens to release additional pressure when the need for performance is high.
Note: This exhaust is designed for the HPA EFR turbo kits and may require customization for your specific application.
