OK guys, wrote to the zoomers corp. about there exhaust system..They state how much hp gains, torque gains, etc. Well when they stated that 2-3 mpgs better, made sense. But then the guy told me it'll all pay for itself in 6-8 months in all the gas savings...How's this all possible. This would only make sense if someones planning on driving 30k+ miles in one year, would i not be correct??? I also want input on zoomers. Don't want drone on the inside, but want aggressivness on the outside, heard they're the best..Plus this is for my mom's car...My parents say it's a waste of $1K just for sound???i need to find someway to let them allow this stuff...She's gonna order a top banana daytona so i've been saving up for it...got any tips, comments suggestions???
