Hopefully they used better vbands than on the MINI. The nut & bolt just look like one blob made of rust. If I look at it the wrong way, it's going to fall apart.

It's nice to just have 2 v-bands to take off and the cat comes right out. It's also tucked up in a spot that would be impossible to cut out. The stock one is on a shelf now and I've got a 49-state legal AA high flow cat on there. A cat, down pipe, intercooler, and a tune is really all that's needed to get an easy hundred hp.

surprised either of those had less than two cats per exhaust stream, seems very un-bmw of them.

Edit: at least in NA market. I know there are some markets where they've historically only used a single cat since at least E30s and thru at least 2013

I don't know, I feel like a stock n55 sounds pretty good. It's still got a smooth straight six noise. It's even better this the MPPK muffler.

Also, n55 is a single turbo with a single cat and a single pipe to a single-in dual-out muffle, the n54 had twin turbos and 2 cats

The tiny turbos they use make it sound like ass..
