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.

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.
