2.7S engine in VW type2 bus exhaust concern!
Hi guys, I'm about to put a 1976 2.7 engine in a 1971 VW bus. The heat exchangers are on the engine, I believe one connected to the other one for a single inlet into exhaust. The exhaust is missing. What should I get? Do I have to stick with this configuration? Is it more simple/possible to have one header on each side connected to a dual connectors exhaust or any more simple/ cost effective way?
Any help/education appreciated indeed! ![]() |

Either heat exchanger should work if it fits in the confines of the bus engine compartment. I think there is no 'cheap' option but if you already have the heat exchangers, I'd try to use them. As far as a muffler, the factory one is hard to beat but is not inexpensive and it may not fit.

Use the 2.7 exchangers and fab up an exhaust or have a muffler shop do it from scratch to fit your new home for the motor. That would be about the cheapest option I would think.

you can go at least 2 ways. trim out the bottom of the bumper to clear the stock muffler or use the late exchangers that exit left front and cut the cat off and weld on a thrush muffler down the left side. i've done both.

I tried a few different approaches and ended up making my own. The one muffler that would fit with the least amount of work would be a Abarth for the 2.2, or something similar.

The top of the apron was cut to match the shape of the engine hanger. I made the muffler to clear the apron and the bumper without cutting. To fit a Abarth, or I also think a SuperSprint would work, I trimmed the bottom of the bumper, which isn't noticeable.
The amount of cutting depends on how you make the rear hanger. I used the same tin on a 2.4E motor as well as the 3.2.
