you probably won't see a difference in gas mileage, so there is no harm in taking it off. Since resonators have almost zero-flow-restriction, the only difference you will experience is more noise at the certain exhaust notes your resonator used to quiet down.

Raspy exhaust help make my VVL sound like a mother fucken BEAST!!! lol and daily it sound just like your expensive exhaust setup. Stay stock if you cant stand a little noise while driving cause i don't think anyone daily there car over 4k rpm.

how much will it be for a none raspy exhaust setup?
-Nice catback set up
-high flow cat
