I got a MadDad cat-back muffler. A local performance muffler shop bolted it up in twenty minutes.

Total cost about $800. Couldn't be happier with the muffler.

The BMW Perf muffler runs $900 to $1500. A friend of mine got a quote from a dealer that wanted a couple hours to bolt it up.

I'd highly recommend sourcing non-BMW performance parts, and highly recommend finding a good local performance shop that is professional, competent & experienced with performance options.

Takes some effort, but well worth it.
