M&K 2-in Sport Muffler Installation on 1980 Porsche 911SC

M&K Dual Inlet Single Outlet Sport Muffler (MKM27) installed to a Dansk SSI heat exchanger setup, and replacing the Dansk muffler. 

The car has Dansk SSI heat exchangers (think headers, but with plumbing to accomodate for cabin heating), and it used to have the Dansk 2-in-1-out muffler that came with them. This upgrade to the M&K 2-in-1-out 'Sport' muffler looks about the same from outside, and is just a bit louder, but it has way more character. It screams. Can't say I feel a massive performance difference, but the volume gives it the feeling of more urgency and sense of speed.

Work performed by Modern Aircooled in Houston, TX.
