Soul Performance axle back exhaust
I saw a post from Soul Performance Products on this site some weeks back promoting their new axle back exhaust system for the F10 M5. It's a straight pipe system like the Turner but has resonators built into the pipes just before the Y-split, to get rid of low RPM drone. This set up intrigues me, as does the low price.
Has anyone here tried out this system yet? Thoughts/opinions?
