You shouldn't expect any HP gains with an x-pipe only an improvement in exhaust sound.

Not a lot!! 0-5 HP. It will smooth out the exhaust pulses and take out some of the popping and gurgling. Sounds like it should increase engine power a lot , shouldn't it?

The C5 exhaust design doesn't restrict that much power, So,,unless you add headers and a good matching collector back system, exhaust gains are minimal. A lot of the power increases or decreases comes from how the mod changes the engines air fuel ratio. If the engine is rich before the mod and the mod causes the air fuel ratio to improve, you see a decent seat of the pants increase. If the AFR goes the OTHER way,,,,well the cars faster cause your wallet weighs less.

I have the corsa X and touring exhaust. Don't notice any power difference with X pipe. However it does sound great on the track at 120

You won't really notice any performance improvement, but if you have resonance or popping from the exhaust, it should significantly help with those issues.
