The HKS Hi-Power Cat Back Exhaust for the 07-09 Mazda Mazdaspeed3 is a high performance exhaust system for drivers seeking a sound upgrade on their system. This exhaust system features full 3 inch piping with a 4.5 inch single exit exhaust tip. Paired with a high performance down-pipe you can expect a huge bump in power and much louder system!

The cat back alone does not require a tune, but when paired with other parts such as a downpipe or test pipe we highly recommend a tune.

Mazdaspeed 3 HKS Hi-Power cat back exhaust

My personal opinion. This is without question the best exhaust for the gen1 Mazdaspeed 3. It sounds amazing and flows really well. Seat of the pants Dyno says maybe 1 or 2 hp. But, it definitely helps the turbo spool up quicker.
