WOW. best sounding mod. FREE.
 

i had some time. and took off the left muffler on my 6i.
had it like this a few months before ( some of u might remember that thread ). but got pulled over.

i got a job now so a ticket wouldnt matter too much.
but DAMN. it sounds nice. like a cross between a subaru's gurgle and msutang GT's rumble

dont belive me? lookit the video i shot
