Help, need to get rid of the single pipe on my e39 540i sport to make it a little more interesting. Having had the E34 M5 for the last four years the 540 is just too smooth and dare i say boring.I've decided on exhaust from either Eisenmann or Supersprint.Need to know what you guys think,any advice is greately appreciated.
BTW coming soon E34 M5 BRAND NEW 6 speed box.Never been fitted.
