Yea, I did a search on youtube for the corsa and the vids I saw the corsa were paired with long tubes. My exhaust is still stock and I want to keep the Bullitt exhaust note, I just want it a little louder. I want to get the JBA shorty because I think it will not change the way the exhaust sounds, but they should make it a little louder. If not then I plan to get ford racing GTA or fr500s axleback.

It is actually a LOT more quiet on the highway. This really surprised me at first because I thought the headers had actually made my exhaust more quiet. I think what is happening is that my engine is running more efficiently now and making more torque, so I don't have to give it as much throttle to keep at the same speeds on the highway. I can cruise at 80mph and still not even hear my exhaust on the highway. This makes sense to me because my fuel economy on the highway did increase after installing these headers. I did have a very slight resonance at 1500 rpms and the headers made that resonance much louder, but it is still only right at 1500 rpms, so its not a big deal. When going WOT at any rpm, the exhaust seems to be a good bit lounder and I can definately tell a difference in the amount of torque available.
