Yes the FR 500 does have a somewhat raspy race car sound @WOT.

But it makes killer power. A for real 10-12 RWHP

You can get the 03 cobra pinion brace from the Ford house.

If I were you I would just get an X-pipe and the cat-back, pinion brace and some gears. It will be plenty fast.

All I am gonna do to mine is change out the springs with some Ford racing 2 inch drop springsd cause I am tired of the off raod 4X4 look if you know what I mean.
