Boosted e46 M3: Vortech Supercharged, Loud Blow Off Valve!!! 

Check out Rob's Vortech supercharged e46 M3! Insane sounds both at idle and acceleration from the blower, loud blow off valve, as well as a really different exhaust tone from the catless headers (eBay), 3 inch single mid pipe (custom) to a Vibrant muffler and turn down tip!
