Free Spirit headers

[OldGeezer]

I am starting to look for headers to replace the stock ones I have on my 04 XB12R and I came across Free Spirit headers. Apart from being really expensive, does anyone have any comments, good or bad about them? If anyone has a set, do they allow the use of a modified RSS & does the front header sticking out pose any problems? And most importantly, how do they work?

Thanks

You can still use the aftermarket Right side scoop designed for 02-07 models, but you may need to trim it slightly to clear the header.
Performance is excellent with these headers and the weight is a lot less than stock. Part of the reason for the price is that they are made from Inconel/stainless which is more expensive than mild steel or stainless steel. We used them for racing in 2003-2006 on our XB12 racers. They will match up to most aftermarket mufflers designed for 02-07 International models or 02-2010 US models.

Please be aware that these will be discontinued shortly once existing stocks are depleted (the headers for 08- models have already gone), so if you want them you need to move fast

Many thanks for the reply and information adrenalinmoto. Are there any dyno results available which show the HP & torque compared to stock?

cheers

Technically kindof sortof. Go look at the exhaust shootout on American sportbike. The micron gives a few HP more due to the hydroforrmed headers. They're larger diameter, and I think possibly equal length. Move more air = more power. So the free spirits are a little larger in diameter so you'll feel a little increase in power maybe. For those though a tune would be the most beneficial way to run them.

How fast is fast? I've been interested in a set of these as well

I'm not sure how many are left in stock at FS but there aren't many, only a handful I think.
