I am looking for a correct muffler for my car BY65 MY66.
Can anyone advice me if this is correct?

I need a Euro muffler and not a USA system.
Don't know if differences in muffler system?
I know the original ones wereproduced by Leistritz.

Can anyone advice me? Or anyone experiences with these of aasesales?
Also looking for companies in Europe who deliver same quality of stoddard or aasesales.

Thanks
