40 Pipe or ?

[Tony Jacuzzi]

I am losing it this is the pipe that I referenced in Ron Z's post re the 40 Vac. The stinger ID is right around .300 on my calipers which is way way smaller than my original 40 parabolic. Dont remember when I got this or from who but it was in my 40 box (LOL) Can someone help out a geezer who has been running too much gas lately.. Tony J

Tony,

I think that is a 20 pipe. Usually 20 pipes come in with a stinger size of .300 to .312.

Hmmm, dia looks like 45-46mm and that is 45 size.......

21 pipes are "normaly" around 36-38mm...

That looks like one that CMDI had CMB make for them several years ago. There was an error made on the muffler stinger. Like they made the stinger size on the OD instead of the ID. I picked up 2 from Andy for a song. You need to replace the stinger with the correct size and it will work great.
