External wastegate size?

[oldsracer]

I bought a downpipe from a member on here a while ago and have a question. Its obviously set up for an external wastegate and my question is this, I'm pretty sure its a 44mm gate but being pretty sure isnt good enough to spend close to $400...What can I measure or check make sure I'm buying the right wastegate.

Side note: It's a vendor's pipe that has been modified to dump the wastegate to the atmosphere and their are no markings so I cant tell exactly who's it is so I cant just ask the vendor.

Measure the opening of the flange and go to tial or precisions website and they will have measurements that you can compare to.

Do you mean the inner diameter or outer of the V-band
