Thanks to all how had replys. I have found the extractors that I want. I will do a dyno-run, then do the mod, another dyno-run and let everyone know the differance.
If it is better,(and I am sure it will be) I will let you know the EXHAUST SHOP to avoid. There was much contraversy to get to this point. If it is better, I will drop of these crap extractors with a note to the bastard.
Wish me luck. :wink:
