Hi all, I don't want to de-baffle the OEM's, 'cos that's a 1-way ticket if you get defected. I understand that Staintune have pipes for the M50 that are still legal, but sound much better, give an extra 5hp and reduce weight over the OEM system by about 5kg. Anyone on the forum have these pipes and how do they sound? I don't want anything too obnoxious, but a nicer note, increased hp and less weight sound like a winner to me. Any/all thoughts or advice most appreciated. PS - how can I change my display name from BlueVeeFour to BlackVeeTwin? LOL!
