Fitted Zaustworx decat pipes to replace rear cats. Something I've been planning to do for the 5yrs I've had the van, a 2005 E51.
Don't sound much different from inside, haven't done enough miles to say if there's any mpg difference.
The pipes are very well made, come with gaskets and nuts/bolts. Pretty straightforward to fit on both pipes.
NB the cats I took off looked immaculate. My van is a camper conversion and we don't use it for short journeys so probably avoid most of the issues with cat degradation/blockage.
Very happy.
