what bender tripples do i have?

[livewire_101proof]

Got some tripples pipes from a relative. Brand new benders, dunno what their for though. They look similar to srx pipes but the header flange and pipes are one piece. The silencer is the tripples trumpet style similar to the bender vip trips I have on my viper but the spacing between the trumpets are different.
Right by the header flange they are stamped VME 177.

Wondering if anyone knows what they are for, if they are high rpm, bigbore??? Thanks

Are there any identifiers/numbers/anything stamped into them.

Only stamping is by the head flanges says vme, under that says the position of the pipe, then under that says 177. Il see if I can get a pic, I have been looking at pics of bender pipes and im thinking they may be for an Sx or something like that
