Exhaust stack for a OS VF 61
I have a new in box OS max VF 61 that I plan to use in my Dirty Bird ARF. I need the little short bolt on rear exhaust part so I can attach the tuned pipe. Can anyone help me out please.

If you are talking about the little short exhaust stack coupler from OS for the VF you do not need it when using the Macs 3682, the Macs header bolts directly to the case.
The 3682 is 1.5" rise which should be good for the DB. You can also get 1" rise (3684) or 0.5" rise (3683) from Macs (look under header => marine and special application headers).
Macs shaped the header plate so that the shape of the exhaust port matches perfectly for better flow. I currently run the 3683 with my 61VF and the header/case fit is perfect. The headers also work with the 61RF and Hanno. Very good product and good price.
