This is the HKS Hi-Power Exhaust System. The design removes any restrictions to the exhaust flow that is associated with the OEM design, allowing your engine to exhale much easier for improved horsepower and torque, all while creating an aggressive exhaust note.
Installation was fairly easy once I got the old rusty OEM exhaust off. Was surprised how quiet it sounds at idle. Cruising and WOT it has a mild tone, absolutely no droning. Once I get the HFC’s installed it will have a more aggressive tone but still not obnoxious. Packaging was excellent. Happy with the HKS catback exhaust.
