My new 1995 540i/6

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

^ What Earl said, don't hack up the Dinan.

You could sell the dinan and build a custom exhaust for not much more.

[jc43089]

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.

[Earl]

And this guy would be interested in the Dinan exhaust and throwing you a 525 exhaust to use for parts

[jc43089]

Even if the 525 exhaust doesn't match, the flange probably does and the bends can be used to get the muffler and tip where you want them.  Then you have a removable custom catback.

Boom!

The eisenmann system looks to be the same for both 525's and 540's here.

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.

Thats what I was hoping the Dinan exhaust would sound like under load... Welding in O2 sensor bungs is not an issue on the custom exhaust.

[Earl]

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

[PerryLa79]

Don't straight pipe it that's way to loud I know already.

[PerryLa79]

Earl did you the system me n my buddy did custom it sounds amazing

[Earl]

The catback portions of our exhausts should be the same from what it seems. If you do ditch the Dinan catback portion for custom just let me know=)

[PerryLa79]

I wished I could post a video of it

If I swap out the cat back for custom then the cats will be replaced by the resonator and all I will need will be the dual pipes going back to the new muffler. If the 525 rear system will make that work then I have no problem with swapping with you. Be easier then bending my own pipes and less expensive.

[Earl]

We will have to get together some weekend and take a look=)

[BMWben]

I'll be back in Wisco on May 13th and I'll start living with Chris in Milwaukee on the 18th or 19th so we will definitely be able to make something happen. I would like to get this system on as soon as possible so I can enjoy it
