				Flange for Cat/Premuffler
			 
			
			I'm accumulating parts for a custom 1-in/2-out muffler (Magnaflow, stainless), which will be mated to a M&K premuffler (and also the factory cat). I'm looking for a stainless 3-bolt flange to match that of the premuffler/cat. Is the 2.5" one shown here the correct fit? Thanks.

			Most decent custom muffler shops can either fab one or have it hanging on a shop.  Common size and shape.

			I think that is a similar flange on my Cayman S to R exhaust mod. Between headers and exhaust. Also, same as I have between B&B headers and my Magnaflow exhaust mod. Gaskets from Porsche dealer. (Cayman part) I am wondering about the size? 2.5 seems pretty big. I measured up my Eberspacher center muffler from a water cooled S that I am going to switch out with my magnaflow muffler. It is 2.25" See pics
