Need help - dump length on Real TH 3.5" downpipe

[Eticket]

Can someone with a real Terry Houston Stainless 3.5" down pipe measure the total length of your dump pipe for me? I think it's 12" including the flange but want to be sure before I get this welded (before I get my exhaust system back on to test).

Only TH 3.5" down pipe owners respond please.

Thanks,
John
