Eberspaecher part #

[cory58]

Need to replace the muffler on my '92 vert and have narrowed it down to Eberspaecher. As I search the Internet, I'm finding at least 3 different part numbers for an E30 muffler. Here is what I could find.

WO133-1662985
18101719238
21.386.84

The first number shows up in current listings for sale on different sites (Amazon, Parts Geek). Does anyone know which is the correct number?

Thanks, Cory

The middle one formats to a BMW pn. The top one looks like it's from Whirlpool :)

Bosal is half the price ansa about 1/3 less.

Thanks Jeff. I liked the Ansa on my Alfa Spider, but it never saw salt (and very little rain) and only lasted 6 years of very limited use.

The 'vert is my "forever" car, so I don't mind spending the extra money to get OEM. Just don't want to order the wrong part.
