Good fitting exhaust for 1600 DP

[15W40]

I have a 1966 standard bus with a 1600 DP in it. It currently has a bugpack style header on it into a glass pack. I put new gaskets on it and it still leaks at the donut going out of the left heater box, which I’ve read is an issue. Im looking for the best fitting, not obnoxious sounding exhaust that works with heater boxes. Would the stock bus muffler negatively affect performance on this motor? Are there other options I should consider?

I currently have a stock muffler on my 1600DP and it runs great. Sounds good too, seems to pull hills better than when I had headers on and the bugpack on it. Also heat risers will work a lot better on stock muffler than headers.

Since you don't have a big high performance engine, I'd stick with stock.

If you can get your hands on a stock muffler for a bay window 1971 and up with the 1600 DP motor, you would have the exact match. The muffler is essentially the same as the earler one but the tail pipe has a slightly larger ID. The only drawback is, that the single piece tail pipe will need some massaging to fit past the bumper.

I know that motor war not offered as an option in the US. But maybe some mufflers made their way accross the pond.

Use copper RTV on the fiber donuts. They wont leak then

Torque is more important than HP with the buses.

If you go with stock muffler first check if the doughnut seal fits somewhat snugly onto the rear pipes of both Heat exchangers. If those seals are loose the pipe of the HEs has corroded down in OD and that will cause exhaust leakage there. You could have a local muffler shop make and weld on new pipes to fix that.

Yes, there are the quicky fix pipes that one can hammer into the rear of the HEs, but the inner diameter is smaller than the HEs pipes. That will cause more back pressure for the exhaust.
