HKS 2007-2009 Mazdaspeed3 Hi-Power Catback Exhaust
This HKS Hi-Power catback exhaust system fits 2007-2009 Mazda Mazdaspeed3 BK chassis models with the 2.3L MZR-DISI turbo engine. It replaces the stock system from the catalytic converter back using full 75mm 3-inch stainless steel piping that flows into a single 115mm 4.5-inch left-side tip for deeper exhaust note and improved throttle response. Pair it with an HKS downpipe for significant horsepower increases while the catback alone installs as direct bolt-on without requiring an ECU tune.
