Im going to be buying a 97 GSR this month. I was wondering what exhaust would be best for me?
Here are the qualifications the exhaust system must meet.

A: I drive on the highway every once and while so I dont want something that will have a loud drone at cruising speeds.

B: I want a single exhaust that is as light as possible.

C: I dont want it super loud like an F1 car, or sound like I pissed off a hive of bees and they are chasing me.

D: It cant be made of something that will rust. It will be my daily driver and I will be driving it year round.

E: Horsepower !!!

Eventualy I might add a turbo kit.

Any suggestions?
