No not personally but quite a few have

Jetting (and I assume your on a carbed bird then)-Road legal pipe-just slap it on but if you have the normal carbed flat spot at about 5/5.5 thou then get it dynod and jetted anyway.
If ya going for race - dynojet and dyno the bike

Stand - It depends what make you fit.Manufacturers will tell you if centre stand needs removal.

IMPORTANT - If you are going for a full 4 into 1 system and have chosen a brand,Find someone with the same and ask them (or look) to see that the down pipes & collector aren't too close to the fairing lowers. There has been the odd case of lowers melting slightly because of lack of space between pipe and fairing lower. It doesn't happen with all brands and have only heard of this a couple of times - Just worth a menral note.

Had a Micron full system on carbed bird

For 4yrs....No probs with fit at all... ie. centre stand still on !
Still a flat at 5500rpm so. as Ben says, needs a jet kit/dyno...
Too many kids to be able to invest more funds thou :violin:

Have a 4 into 1 full titanium Blueflame fitted (the one where you can remove the plug to transform it from road legal to full race), power commander is recommended if yours is injected, or rejetting if carbed.
Re. centerstand: the stopper is on the left pipe so that's a problem - a problem solved with a clever bracket soldered at the right place by mister 1200Pete - the weight gain without the center stand isn't more that what you'd gain with not eating for 2 days, and center stand is def a advantage in town... And anyway if you choose a full titanium 4 to 1 system you gain about 15 kg compared to OEM piping :yo: :beer:

4-1

I Have been offered set up which includes Micron stainless steel 4-1 with choice of end can for what i'm informed silly money ( that i still cant really afford) but if extra work as in running on a dyno is involved it may induce a divorce
( Hmm theres a thought ?)

Edd, if you want to try mine before you buy one give me a call, and as Ben says, watch for the O,S,lower faring melting, :bang: mine did, :mad:
as you've got one of them there carbed ones, my pc11 wont be any use to you , also you "lose" the center stand, unless you do a "spot" of welding :rolleyes:

mariwaki 4 to 1 leading to a Micron straight through carbon end can, :eek: and its FFlipping LOUD, :eek:

and before lumpy gets in on the spellin of Mariwakiday wacka day, I know its speld rong, :f but the spell chucker aint got it on, :rolleyes:

Me too

Yep, despite sliding down the road last week my maroon bird (soon to have a Taffy special paint job) is fitted with a Yoshi 4-1 no problems anywhere. Fitted and dynoed at birth and no problems at all (except its not technically road legal). Let me know if you want a legal way round that for the MOT.
