    rxt255-is supercharged sound

    I want to make it sound nice and deep whistle noise. The oem 1 barely has any noise on the supercharged. Does anyone know what i can buy to make that sound? Do they have some kind of blow off valve or anything? Mine is a 2009 rxt-is 255hp. Thanx for the help.

    4inch fizzle intake or a riva rear air will get you a decent whistle

    The intake makes a HUGE difference. It is a noticeable difference. Before the intake I could barely hear the charger. Here was mine before I did the rear air, exhaust etc. This video was with stock exhaust and 4" front intake.

    Thanx. I will get a 4" intake. Is it hard to install? I see that that rxt-is suspension stuff, it seems like there is no room to work on this machine.
