?'s about removing cat...

Will it improve the exhaust sound and how much, if any, horsepower increase could I see? I am planning on just replacing it with a straight piece of piping.

It'll definately be louder, as well as a little more hollow sounding. You may or may not like the sound, depending on your preferences. It also dosen't sound the same on all cars. I like how mine sounds.
