i have a white brothers e series pipe on my bike now and it just had a 119 on the db meter with all the fins and a 109 with the minumum (4) the quite core said it would only drop the reading another 4 or 5 db's. i took all of them off and the spark arrester and i got a 112 (sounded awsome ). what new pipe should i get? i want something carbon fiber just cause its cooler but i'm not looking to spend a whole lot. all i need is a slip on.
