Has anyone tried this pipe on the VAC 91?

Thanks Tim

I ran the Silver version on my SAW Boat. It was the best for High RPM.

No tunnel , somehow this ended up in the outboard forum .lol

I am replacing my old Picco 80's for a pair of VAC91 motors in my twin.

I have been using the AB pipes on the 80's and was very happy with them.

Also have a new pair of the out of production Rossi pipes to try.

I am also really surprised how thick the header wall is for this motor , heavy duty. B)

Yes and they work extremely well.

I have a set for sale that have had header sleeves welded on that I am not using now .

The 90 JagIII that's won US1 and several large events like Hobart 2012 has the VAC .91/ Black CMB .67/.80 muffled pipe (same as AB's) set up.

I'd say it works okay.

Also, the old Rossi pipes are SMOKING fast on Foley's VAC .91 twin.

I will let you know how it works on my 1.01 real soon.

Not a good 1.01 pipe. Ran it for awhile on my SGX 1.01 until I figured out that the AB 1.01and Macs 15cc was WAAYY better.

Wish I could get another AB 1.01 pipe. the MAC 13cc opened up stinger works killer.

Opened up the AB60/80 stinger to .500 will see if it rolls with a .125 spray bar, fuel line and pipe pressure fitting.

Going to stretch this thing out.

Bin to 27700 with the 13cc with a .470 stinger on my old 1.01 will see where this one goes.
