It appers to be a 2-1/2" set up. I don't think that'll fit through the cross brace on the 'vert. However, I am playing with an idea for an extension made out of aluminum plate.(actually, a copy of someone else's idea)
This 2.5 was designed to run through the brace. The mock up was at the T/A Nats last year. I asked a million questions before I made my choice. I'm still in debate as to how I want to terminate the system; cut the ends to look like factory or the splitter tips from Ames. Sug-jestions welcome.
