i've been trying to find a "sliding door" style cutout to avoid some of the the problems associated with the butterfly valve type cutouts.i've seen people talk about this kind of cutout,but can't find any good info.when i make a new downpipe,i want something that has a true 3" opening,and functions beter than what i have now.

scroll down to the bottom to see the 3" model.. what he uses is an adapter piece that goes in between his cutout and your 3" flange
