Someone posted on this board a while back, this kit for your mustang.... I don't remember all the details, but this is what I recall. You put these "valves" on your exhaust pipes, i think after the cats, but before the mufflers... And you can close them or open them as you want (from inside the car). Leaving them closed lets you drive street legally with your regular exhaust note, but when you want, like on the strip, you can open them up, allowing exhasut flow to bypass muffler and shoot right out, making a lot of aweomse sound.
Anyway, If ANYONE remembers the website, or has comments to make if they remember the name of this product, HELP!!!
