Stock for stock it definitely sounds better than anything they make today. Especially the M3/4 which continues to sound like total ass. I would really like to know who greenlit the exhaust tuning on those cars, they are easily the worst sounding stock BMWs of all time, and probably one of the worst sounding I6s. It's especially baffling since they sound a bit better with those goofy wavy midpipes that are available now, all it took was making the lengths equal-ish.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 catsLeave a comment:

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.Leave a comment:

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 2013Last edited by Northern; 04-11-2024, 09:38 AM.Leave a comment:
