I need a new muffler.....1971, 1.7L, what are my options? Options

Hi -

The Bursch exhaust on my 1971 1.7L is beyond repair at this point. I unbolted it and need to purchase a new unit. I am pretty open on replacements, meaning I don't have to replace it with another Bursch (of course would like to keep the price manageable but that is another topic...). With that said, minus the Bursch, the car is bone stock and so I would need a new system, the gaskets and the associated bolts as they are not in good shape (I am unsure of the bold size, any help there appreciated too). I did the measurements from a picture I found on the site and I definitely have the dimensions for the 1.7 L HX.

I read in another thread that the tailpipe on a vendor's unit was not compatible with the stock rear valence, so I guess I need to avoid that unit (Dansk?).

I know that 914rubber has a stainless steel system too - anyone have any experience wit that one? Any advice appreciated. Thanks in advance.

Best,
Reg

i pulled the old muffler down and took a good look at it.
its definitely a replacement not original from factory.
has a 1983 date stamp on it.



i thought it had a LANGE stamp on it somewhere but must be my imagination.
def not an ERNST or a LEISTRITZ because they did not weld the little reinforcement tabs on from the inlet flanges back to the body of the muffler as far as i know. but its german.

it is exactly the same as this one that was on a 74 1.8 that was sold on BAT a few months back that was a pretty original car.

you got to wonder what these cars might have had on them original from factory. i'm going for the 412 left hand side exit pipe like the unique one that was posted on a thread a few years back. but then they became unobtainable ? and the inverted bus muffler became the replacement part?



@potomacmidget
while i was snooping around i found this early car on BAT fitted with later muffler as per 74 and its pretty clear its got a unique tailpipe to let it get out the early valence.
must bend back slightly after it exits muffler and then bend out through the valence to get through the original tailpipe hole.
either its a custom fab tailpipe or you can / or could get them.
