    Because it took a little too long and I wanted something a little more aggressive, I went with the HKS axle back exhaust. But I’m lote than ready for the turbo kit and header that’s in the works. Maybe you guys will be able to provide and engine rebuild later down then line as well

    I bought the 60.5mm catback within a week of getting my 16” hatch m3, are you guys able to take it back for the difference of the prices or would I have to buy a new one entirely? You guys rock thanks for keeping us m3 people in the loop on your future plans.

    How loud in decibels is the new 80mm cat back exhaust for the mazda 3 2014+? I am wondering if it passes the CA Exhaust Noise Law..
