What milage are you getting 20mpg, 18mpg??? I bought a S & B cone filter and I drive like the cops are chasing me all the time (plus all my driving is aroud 10 - 15 min stop and go driving) and I got 18mpg w/ the stock filter, and 20mpg w/ the S & B filter. So there's a soulution, buy a K & N or some sort of cone filter, not sure if that will viod any warranty though.
PS The sound is AWESOME too!!! Just a tad louder.
