Exhaust Port Diameter

[JonS]

can someone tell me what the diameter of the exhaust port is? i need to buy an expansion plug today so i can run my leakdown test. i don't have my blaster in front of me or i would measure it myself. if anyone can help it's appreciated and rep will be given.

good deal man. i went ahead and picked one up and it was wrong. it's a 2" and i'll just return it tomorrow and get the right one.

FWIW if you have a choice get the one with the bolt and washer.
That way you can tighten it for a really tight seal.
