This exhaust I originally bought for my 13 skyactiv to give it the dual exhaust look I did a bumper swap to make it fit and it sounded great on that car. I decided to try it on my 2.5 since it was laying in my garage and we had a couple of nice days since the exhaust was originally intended for the 2.5 I thought why not I Installed it literally drove a block and removed it. sounds so bassy alot of bass vs the skyactiv 2.0. my question is why does it sound so low and bassy on the 2.5? is it the exhaust manifold? does the larger bore really change the sound that much? I personally hate bassy exhausts they have this deep bellow like your blowing a long horn I know some people like the deep sound no offense intended.
