I need a complete Magnaflow exhaust for 64 my Malibu SS

Could I use a 2.5 or 3.0 ?

Is there a different sound with both ?

I will be in Cocoa Beach (Hot rod Power Tour) and in Goodlettsville (Chevellabration)
Will it be possible to buy a complete kit there ?

Thanks
David

If your over 500 HP then 3". If you are under then 2.5". I wouldn't suggest the 3" unless you are over 500 HP.
