Rear lower valance
wonder what it would sound like with just GT500 takeoff mufflers? I'll probably just wait for the frpp kit
I'm just going to assume you meant 4" tips. A 4" exhaust on any Mustang, short of a 2000hp turbo drag car would be utterly ridiculous.
Yes, that would be ridiculous. I meant just the 4" tips, not the piping. Just something that'll fill out the diffuser better than stock.
