Surely an exhaust and few mods would see you past 220kw anyhow.

They've got better flowing heads and a few bits and bobs.

Some of the very first ones had pretty trick alloy ones I think, then they started making 'em out of steel, which added a bit more weight, but performance was the same.

Yeah you can get past 220 no probs with an exhaust and stuff, but do the same mods to the 220 and you'll always be at least 20kw, if not more, ahead.

The average punter may not care much about the difference but anyone who's into modding cars would want the 220 - it revs a bit smoother etc...

I have recently purchased a 1999 AU Fairlane Ghia. 135,000km, 5L Windsor, LPG. I am considering putting an exhaust on it. Have read in this thread that a gain of around 10kw can be achieved via a twin exhaust. Is a twin the way to go or could I get a similar result from a larger single?

Single 2.5" mandrel bent will be the best system for that. Just make sure its mandrel bent, not pressed.
But if you really wanna spend the money, go a twin 2 1/4" system. That will allow for any future mods you may do. I made 300+rwhp through my twin 2 1/4" system and made it very torquey.
