Not just powerful performance with quiet sound! HKS designed this cat back exhaust to result in a dry sporty exhaust sound that can be heard inside the vehicle at the step of a pedal. In pursuit of the ideal exhaust system, they used a 75mm straight structure which generates the lowest exhaust pressure while maintaining comfort inside the vehicle.

Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.
