def by far the best bang for you buck mod of all times....well, actually no $$ at all for a completely different feeling and completely different sounds....by the way it has to be in sport+, if im not mistaken... and you bought an ///M car which that would normally mean its going to be louder and more obnoxious than 90% of cars on the road...If your so worried about how loud it is just by doing this mod then you should have bought an electric car
and who cares about your neighbors...I know if im spending 80$ on a sports car, I want EVERYBODY to make sure they here it
...they will get over it sooner rather than later...take it from my experience lol
