My new 1995 540i/6
-
Stock e34 525i exhaust. I can't find any threads on people swappung exhausts between 540's and 525's but they do say that they are routed the same way and are very similar. That leads me to believe they would swap fairly easily. We can get together some time and look at them side by side.
I believe the 540 has a duel 2.25 all the way back and the 525 is probably only a single. They look similar from the realoem diagrams but not exactly the same.

Hopefully Dominic will chime in but since I've ridden/driven his car I can attest to it being very quiet on the highway and during city driving since the stock resonators are still in place. Check out the videos he posted on his gopro mount thread.
I've heard Mike's 528e too and it sounds good too.
I agree with Earl, even though the Dinan exhaust might be tired it still could be sold and a stock catback would be a good candidate for a muffler delete.
I have no real issue with any drone or resonating except at ~1800-2000RPM. Even then, it is by no means unbearable. After I cut off the muffler I did not put a straight pipe in its place. If I were to do that, I am almost positive that the resonating would go away completely.
I would like to hear what he did to his system as well. Chris showed me videos though and it is great.
I am not sure how the exhaust is routed on the e34, but for mine it was very simple. All that I removed were the two scuba tank like mufflers at the rear of the car. (Cut it with a sawzall about 4" beyond the rear axle if I remember correctly.) I still have the cats and resonator in place. Eventually, I plan to extend the pipe to the back of the car, just haven't gotten around to it.

Looking at realoem again the systems look pretty different. When I get home I'll probably end up cutting off the rear muffler and seeing how loud it is. If its to much then I'll throw a magnaflow on there or something, maybe a dynomax vt. Can't do anything for another month and a half still.

Why not find a stock exhaust and hack it up? Cutting up a perfectly good Dinan exhaust doesnt make sense to me. Especially since there are more e34's in the junkyard than on the road and you could score a catback off of one of those for way cheaper than you could sell the Dinan

Even to make a temporary custom exhaust costs almost nothing, Mike and I made a full custom exhaust for his e28 and the only expense was 30 bucks for a glass pack and 15 for a shiny tip. There are plenty of guys over there that could weld something together for you.

What John said my e28 sounds nasty and all we used is was 2 old exhaust systems and i can be safe to say that my e28 is the only one with a custom x pipe with cat delete and only a glasspack with a truly centered twin chrome tip setup!

Good news! Chris was under the car the other day and said it looks clean underneath, always a good thing. Also, he saw that the muffler should just unclamp from the rest of the exhaust making it much easier to see what the system is like without it and then throwing it back on if it is to loud. Also I did some looking around for Magnaflow mufflers and I found this beauty.
As you can see in the video is a Magnaflow, I just called Miller Performance and was told that the build used the muffler #12468 and resonator #11379. I would like to go with this muffler/resonator because it doesn't just sound like an american muscle V8 like other magnaflows which was why I was a little hesitant of going with them. It has more of a sporty tone to it or european I suppose, I like it a lot. One question I have is what are those ball looking things before the resonator, cats or what? Not that I necessarily need them I'm just more curious. Another thing is how am I going to keep the O2 sensors? According to this real ome picture, the O2 sensors (#21) are in the front of the cats. Can I just put new piping there and screw/tread a hole for them? I don't want to cause any problems with the car running rich, V8 mileage doesn't need any reasons to get worse. I suppose the O2 sensor could be in a different spot on the Dinan exhaust but if I find a different exhaust to chop up then I'll need to figure this out still.

The Dinan is a catback and not a full exhaust isn't it? Welding in new o2 bungs is quite simple.
Just another reason why I need to learn how to weld. I don't know about the Dinan being cat back or full either
