VAC 91 pipe

[Joe Warren]

Went out testing today & thought I had the magic pipe for the VAC 91 a OPS90 pipe. Well it does not have enough Volume. I have tested the MAC13cc Pipe for a VAC 91 twin. Anyone testing a Single engine hydro with a VAC 91?? I was not impressed with the VAC91 muffled pipe on the Twin. jw

Hi Joe Sold VAC91 to me I installed to punch flare swollen pipe (Brown 67 Parablic pipe)and the new header 22mm long fit tapped onto the it and set up 12.75" center glow and point belly line. I drilled 7/16" hole into the pipe stinger . I am very glad that "THUMBS UP" Best of one this kind pipe. really fast ( Vroom)and very low to high speed No problem! Use O Donnel glow plug both #99 and #89 Great working
