Help me decide what model of spintech muffler to use on the 466 BB. Loud is fine with me as you can see I have 1 ch flows on my 5.0. Im worried that i might get that droney crap when you let off the gas, you think that might happen on like 9.5-10:1 compression? The system will be with Hooker Super Comp LT headers and custom side exits.
