Single Inlet GT3-Look Muffler Installation

Congratulations! You have just purchased THE highest quality lightest weight muffler for your 911 SC or Carrera. Installation was designed to be very simple with only metric wrenches needed. Please email or call if you have any questions or need assistance.

Screw driver, 13mm wrenches and 11mm nut driver is all you need to install the MKM73 Gen III muffler shown. To begin, slide on tailpipes and install set screw. Lift muffler into place and install one 13M bolt loose.

Install smaller strap (optional) on driver’s side and larger strap around heater pipe on passenger’s side.  Leave all loose.
Remove 13M bolt and screw out telescoping inlet flange until it meets the existing pre-muffler or car outlet.

Adjust tailpipes plumb and on center. Tighten straps first then flange bolts and clamp. Install rear valance.

Enjoy!
