What's the best size TB to match a 3.5" pipe?

[STANGateURlilSS]

for future reference... 1 inch = 25.4 milimeters..

Thats a more accurate way than the 25.4mm one. Not that it's a big difference but when your machining it can make a difference lol.

89mm

That's backwards. 1 inch = 25.4mm exactly. Using this conversion is more accurate. You are rounding when using the inverse, 1mm = .0394 inches. Actually, 1mm = 0.0393700787401574803..... inches.

I figured I was safe going out to the hundredth of a thousandths decimal place.
