914-6 Mufflers Options

[patssle]

I was under the impression that 911 2 in / 1 or 2 out mufflers would work for 914-6 cars. Am I wrong? I picked up a Dansk 2 in 2 out muffler that a friend let me borrow and it doesn't fit. The OD of my MSDS headers are 26.5 inches. The OD of the input flanges of the muffler are 27.75 inches.

I don't know what to do now! Everything I had read said 911 mufflers will work great.

That muffler hanger looks to be for a 1.7 or 1.8 liter car, and won't fit the -6 muffler.

If you're not sure about the headers, give Martin at MSDS a call and he would know if there's any issue with the headers. He's a good guy and his stuff is top notch.

obviously, you need to leave off the lower valance or cut a notch for the other outlet pipe from the muffler if it's two out (bullhorn style). A 'sport exhaust' muffler should exit under the later style rear valance without clearance holes.
