I got mine direct from blueflame. Payed the same as im gauci 525 for the system including 3' 200cell sports cat. When i first got it it was soo loud and thought id made the wrong choice. But now ive had it for a month its coked up nicely and is very subtle when your just crusing at town speeds. Jump on the loud pedal and it sounds like a rally car, spits and pops alot under heavy acceleration. LOVE IT! And its got the nice big oval tail pipe thats looks the nuts on the beeza. Get one, you wont be sorry!
