Yeah i hope one comes out soon, that hp would be nice. Im trying to find some kind of exhaust too.
careful with the exhaust. You should get ones that are advanced or you will gain HP but sacrifice torque, which will cause you to lose drivability at lower speeds. Get ones that actually allow pressure to build up at low speed and open up as you gain rpm.

What do you mean by advanced exhaust?

Acyes, What brand of exhaust are you getting? where did you find it?
on simple after markets exhaust system, which open up restrictions on the exhaust you lose tq/hp at the bottom end, and gain HP/tq at the top end. This means you will lose power in the range you mostly use your vehicle to get around. For instance you will lose Torque in the 2-4.5rpm range but will gain in the 4.5-6.5rpm range. So to tap that extra power your going to have to be revving up high all the time or in racing situations you will tap it. Realistically, we all use the vehicles to get around town and on highways. So you have to ask yourself if its worth losing power in the range you will be using your vehicle most to gain a small increase in HP/tq in the high range.

You have to have a certain amount of restriction in the exhaust to keep your low end torque up at the lower levels of RPM so SOME manufactures of exhaust systems have devised a method to prevent this loss of hp/tq at the lower end. They have made it so the opening is smaller at lower rpm creating back pressure and opens up fully as you get to the higher rpm range thus giving you the best of both worlds. When i researched this it was a few years back when i had just bought my mazda 6. I have no idea who offers this at the moment. SOme people just get it for the sound and thats fine. Just wanted to give you a heads up if you're doing it for performance gain.
