2007 BMW 328xi Top Speed Muffler
Four months after I got the Top Speed muffler installed, I did a few revs on Winter morning. First revs were to about 4000rpm, then a slow rev to around 6000rpm. Then 1 fast rev to 6500rpm. Watch my video of the stock exhaust for comparison. Look on ebay for "e90 top speed"
