I see the baffle has to be cut out, But I am curious about the throat and how much material might be removed. They say it goes from 76mm to like 55mm.

I am curious how much meat is there and how much can be removed.

I have a few more projects to wrap up before I can get to it.

Was just hoping to see what I might expect. Wasn't sure if it was like opening up the short side radius on a head once you get the baffle out.

Did the baseline Dyno today on the local heart breaker.. Made 278hp/ 358tq peak @ the wheels. The pull with the stair step in it was with the stock tune and the other one was with the 91octane tune we did. K&N cold air intake, 180* stat, and a muffler, custom 91 octane tune.

This was the baseline before I do any engine work.. I'll strap it down again after I install it and get the tune sorted..
