HI all,
Did anyone of you drive a Mazda 3 Skyactiv-x (bp) before and after a Remus exhaust modification that Mazda sells?
Would you say it changes the fuel economy?
Also, I would like to know the same in regards to the sportier Mazda front bumper/side skirts/rear bumper/spoiler.
Thank you so much for any replies!

The only way fuel economy can go from a modified exhaust is up, but your baseline expectation should be zero.
