2014-2018 Mazda 3 Skyactiv Engine and Performance
Hey guys, new to the forums. Just bought my first Mazda. 2017 Mazda 3 Sport GS. 2.0
Looking to start building up her performance. I have been lurking the threads over the last few days and seem to find people installing AxelBacks more often than CatBacks.
I was hoping someone had some insight...
