Custom cat back on my bimmer

[Adam Brooks]

Stock one broke right after the cat after the welds brroke (last time it was replaced they elected to weld a stock on in vs unbolting the thing and putting it back in normally.. dont ask me why)

I elected to just have new stainless pipes ran from the cat to the stock muffler eliminating resonators. BMW stock mufflers flow great from the factory and aftermarket ones have a marginal impact on performance other than sound *if* you are lucky. I've had aftermarket mufflers on before and all it does it attract attention.

So in this case we just elimated the resonators and saved a bunch of weight. It actually sounds perfect imo especially under load flying under bridges and tunnels.

Ron did an excellent job and by far the best quality work that I have seen before on any exhaust project.
