You can easily see where the two 2.5-inch mandrel-bent pipes from the header collectors merge into the Y-pipe before the catalytic converter. The Muffler Man makes its own Y-pipe bells for situations just like ours. (You can call Lee at (714) 524-7818 to buy one for your own system. They run about $20.) The outlet side of the Y-pipe bell is 3 inches, which matches our 3-inch Dynomax Super Converter perfectly. From the catalytic converter outlet, it's 3 inches (stainless, mandrel-bent) all the way out.
