I had the akra evo race line exhaust and planning to switch my akra header to the dms header. However, i think my akra muffler only have one inlet for the header connect pipe (the dms has two pipes connecting to the muffler).

Anyone know if there is a top inlet hole on my muffler that is just covered up or my muffler only have one inlet hole for connecting pipe.

 

The akra should have two plates covering the upper inlets on the center muffler, they use it with the street style exhausts that maintain bypass. I have installed a set of Dundun's in place of the akra headers and maintained the TI center muffler on an RS. Should fit the same way on your car. You will need to get new exhaust donut gaskets (between side muffler and center muffler under the bolted flanges (if you haven't been that far.) The Akra 90's stretch the graphite gaskets just a little too far to seal on the DMS inlet pipes and they are most of what holds the pipes into the muffler.
