Exhaust performance numbers?

[Vibe GTR]

Does anyone know which exhaust for the GT gives you the best performance, money not a issue?

uhh my straight exhaust gives me around 16 i believe...my friend dynod one on the celica gt-s and got that with the straight pipes. But down low i lose alot more hp and torque then an exhaust system. My gains are really high end. A normal exhausr system youll get around 8 hp and 8 ft/lbs of torque high end, but wont lose as much as me low end.

I honestly don't think there's anyway you're making 16 at the wheels from exhaust alone. Maybe 5, but 16, ain't happening. Get it dynoed. I 'd like to see the numbers from an open exhuast.16 HP at the wheels would push you close to 190. I just can't see those numbers from the lack of an exhaust.I'm not trying to be a jerk. It's just sometimes things get inflated. Without real proof, you can't claim numbers.
