Thanks for posting the graph even if you cant compare the gains. The CNT definetly is a well made exhaust and the price point is a plus. Its definetly not a flashy, bling-bling, loud, attention drawing exhaust system; but thats a + or - depending on perspective.
It's a rather quite exhaust compared to others; I'm not buying it for the sound but have you heard it w/ HFC's? WOW. I got mine in the mail.
