Nope. I haven't got one (yet) . Hope this helps.... 

Think of how stupid the average person is, then realise that half of them are more stupid than that.

Jemco in the US & Zenshin in Japan make GT550 3-into-1s.

Re: GT550A top end woes
Think it have to be Higgspeed seperate expansions.can wait til spring.the 550 running fine but 2 pipes have loose baffle plates and although ive managed to jam them straight at mo it wont last

Re: GT550A top end woes
Wont do much for performance but will sound great just like a Piper in 77 however top end will be killed midrange may improve a fraction.had them on my 750 & 380.not as though its used for thrashing about like we did 45 yrs ago.my ign switch on the blink.may need to fit another.something to look forward to.have put contact cleaner in as a temp measure in hope it will last a while longer.
