I've been in contact with Dennis Foran (well known Aussie maker of custom exhaust) about the possibility of him making headers similar to the Perfect Storms. I first spoke to him months ago but it has only just now started moving forward at all. Not wanting to hijack anything Tex is doing but it may prove to be more cost effective to have some Aussie made ones for us here. In any case, he's only giving some consideration to the feasibility and cost first so it can't hurt to have a couple of options. Just one thing for anyone over here to consider. He's asked if anyone has a bike he can have access to. If need be I'll provide mine but thought I'd see if anyone else living nearer to Gosford can do it. All hypothetical at the moment but please let me know if you're interested - in the header and providing your bike.
