Vmax 600 twinpipe shootout, anyone??

I do remember seeing Bender & RPC pipe dyno sheets..Both were almost exact..Dyno Tech has the results..I do have a set of GYT twins that work very well,but never seen any dyno sheets on them..I went by advice on going with them and not sorry for using them..
 
I know aguy that had gyt's also and it pulled very hard was really an improvement.I think MrSled has a set for sale.
 
I also can speak on the GYT twins. Have a set on my 96 xt and they work great on the tank. The stock 96 GYT single went on my 95 and showed a little improvment over the stock 94/95 pipe as well.
 
I do have a set Of GYT's for sale...They are on my 700 twin now..They work as that video shows(Lanzi's 2/25/07..you tube) They are brand new,only used this past season.Just raced,never trail ridden and always in a inclosed trailer..$200.00 if ya want them and what ever shipping would be..

By those numbers it would make sense that they are at least close to the Bender Pipes. Mine Pull hard to about 7500 Which would fit those specs pretty close. Anyone do any good clutching with those pipes?
 
Regarding the clutching etc for GYT twins, I believe I still have the paperwork at home. I will look tonight. The recomended new spring and helix. Also the head gasket mod works well with these pipes. We did all three and it made a BIG difference on the tank. This sled felt heavier than the v-max 4.
 
My 700 BB racing...8BU's no rivets,Bender orange spring,4mm in shims,49/41 helix,Bender Viper secondary spring at 40' twist....For trail I would say 8CA's and 45/41 helix..
 
Thx Inline and mid 90's I will look into it for the next winter I don't mind the shocking pull when the pipes kick in but i know it would go a lot better and faster with the right setup, as right now it kicks in at 5700 and pull to 7500 35mph roughly to 75-80 the 35 is the part thats kinda bad on the trail :)
 
Thank's bob.I thought there where like two years that gyt's where made by bender than they switched to power inc?
