I dont know if he has but I went to the track yesterday to do some good running with the bigboy pipe and I LOVE IT!!!!!
super smooth yet tons of power....ran the motor at between 230 and 238 for 5 consecutive tanks...
started timing them on the third tank
1st run went 11 minutes then pulled it off when it started to get lean
2nd tank went 1120 before it started to get lean
3rd tank screw it I ran it out of fuel at 1155....
I dont like to run it out of fuel but had to test my gas tank mods I did due to my last issue...
I race in the midwest area and I was running it a tick fat just due to not wanting to mess anything up, for me this motor and pipe will go 12 easy when its all said and done..
doesnt quite have to super cool sound of the 2013 but it still doesnt sound like most pipes..

and when it was all over I went back the GRP pipe, thats the pipe I settled on before getting the bigboy pipe and I can still say that this pipe wasnt bad either, runtime was 940 on teh only timed run I did but an unbelievable amount of power, actually a little too much, it wasnt all usable power..
so I still havent got to do a good test with the 2013 but if you guys are looking for a pipe the bigboy should be on the list....
