X pipe horse power gain?

[D-Cobra]

Those of you who already have the Aptens, how much did you gain by adding a catted X-pipe to your car?

I'm thinking about adding a catted X pipe to my car, but I'm a little hesitate about the money vs hp worth.

Also I don't want the car to be super loud, how much more louder did your car get? and around what RPM did it get really loud?

Im also curious on how much power a x-pipe will add....? Im getting ready to order mine!

On a mildly modified '03 Cobra you're not going to see much gain. Maybe 10+ at the rear wheels. You will, however, see a change in the tone of the exhaust. More of an exotic sound. Some like it. Some don't. So if you're not sure you want the X-pipe I wouldn't spend the money. There are better mods to spend your money on in my opinion.
