There's a thread around here somewhere with an e60 and a quad exhaust on it. google search the forum, it'll probably turn up.

the back of the car is probably the same underneath. left side exhaust, same body.

Yes the exhaust does end on the left side but 535i has the exhaust pipes under the body closer to the driver side, 545 and 550 are dead center.

I put my own in.. I found one similar to the Umnitza one. It "looks" exactly like it from what I can tell. I would say get a shop, or someone that can weld.. because what nobody tells you, nor does the picture describe, the exhaust pipe is thick, thick metal. I have never cut anything so crazy in terms of piping. But the real tricky part is that it is not perfectly round, rather oval like. Of course you get the new exhaust, and it's a perfect circle.. there is no way you're going to get it to match. I even had a pipe end expander, tried to round it out well.. but it was futile.

Okay.. so the next part is.. I used a few nuts and bolts, right under the trunk pieces on the battery side, there's a plug you can pull out, and mount your bracket creatively. No need for you to do any extra welding. I asked my friend to help me weld the junction between the new and old.. I just tacked it together quickly, but for my welding skills to go around.. not going to happen. I don't see any "bolt on" going to happen with the funky shape of the piping.

I kept my stock bumper because I like the look. I dremeled the lip to accommodate the tips.. I like it

Here's some of my 535. The setup is a Dynomax muffler on the driver's side (1 in/ 2 out) with a pipe sent over to the passenger side.







No real suggestions. It's pretty straightforward if you have an exhaust shop do it. Just put your bumper on, drive it over and say "I want the exhaust ran over here too".

I wanted to have two mufflers but I guess what you guys are suggesting would be simpler and cost effective.

The question is on cold starts are both sides pushing even exhaust gases?

Unless you put in some kind of valve, yes - it will balance based on the plumbing.

Just gotta say Mike_K your car is pure sex.... I just joined the BMW club at 24 but I am already craving something more than my basic 2010 528i xdrive. I want to do some cosmetic work on it but feel like I need to wait to have something with more power before I dump money into it. Long story short I want your CAR

Just did mine.....07 LCI 530 MSport. New rear defuser off ebay $150 nzd link pipe fitted and 2 new slash cut tips fitted $350 nzd. Just have to take defuser off and have painted back to factory white.

Love the new look, and drive it in tiptronic all the time now as you can hear the car rev...didn't do it for the sound, just cosmetic appearance, but the sound is surprisingly soothing.....never got used to the double single sided exhaust. I know its a European thing. Its a bit louder at revs, but fine once it drops back to cruising revs of around 2000.

I guess I'm the only one that still likes and rocks the single exhaust. Don't mind my buddies M4.

That's exactly what I'm looking for! That's a clean job but I'll remove the factory muffler as well! Thank you

Bro to be honest I like the single exhaust because I'm not trying to replicate a M5 but my front bumper is cracked at the bottom and the rear got a couple dimples so I thought it'll be a good time to update the look. Plus the M5 rear was cheaper than the mTec haha

And I'm guessing you have a BB exhaust I love how they look!

THE original m3 was a single side dual exhaust - quad tip is purely cosmetic (unless it's a McLaren F1 with legit quad tips (lol)).

But seriously - quad tips for cosmetic purposes does nothing insofar as reducing backpressure (and improving performance is concerned). that's the $3k+ realm of headers and catbacks. Adding weight for cosmetic reasons FTL.

dual exhaust 550/325+stahl headers FTW?

Don't get me wrong, but I'm a form through function guy throughout. brake ducts that cool your rotors FTW. faux mustang brake ducts are FTL.

Mike K and Gregonz those are some nice looking diffusers. Where did you get 'em?

I've debated them since I love the look.. I need to get one more specific to my bumper, as I see yours both don't have the rear reflectors? Install difficulty? I have to figure out mine .. but it looks pretty good stock. Since there are few pictures floating around... here's a link to mine.

What kind of tips are those? 3inch or 3.5?

Hi,

I brought this off "protuning.lv" seller on ebay. It was very good quality and it fitted perfectly.

Mine is a an msport model so has a different front and rear bumper. The best option would be to track down a rear msport bumper and the diffuser just fits onto the bumper. There are threads on here about fitting the msport bumper to a non msport model.
I only went with the smaller tips as wanted a bit understated, and not too boy racer looking.
