Wasted Potential Posted November 5, 2017 Share Posted November 5, 2017 I installed a nameless 5" muffler axleback and need to replace the factory flange from the midpipe. I had to hacksaw it in half and it is too thin/weak and leaking... Measurement from bolt center to center of the gasket = 3 & 7/16th" Measurement from inner most portion of circle diameter = 2 & 1/8th" Measurement from outer most portion of inner circle diameter = 2 & 1/4th" You can see the OE gasket within the picture just below the paper - notice the inner (reinforced) circle portion. I am presume that I need a "Stamped (not formed) flange with a 3 & 7/16th" bolt hole - center to center, with a 2 & 1/8th" inner diameter, OR 2 & 1/4th" diameter? I presume that I will have to angle grinder off the OE flange, and just weld the pipe to the flange - the welded portion will be outside (around) the pipe onto the outside of the hole for the new flange correct? Or, is the intent to have the pipe fit INSIDE the flange partially, and to weld the pipe outside to the flange... This seems simple, but I overthink everything. Thank you.
