Will keep you all updated, but I just ordered them so I’ll keep u all updated

http://www.armmotorsports.com/BMW-F1...-tu-dp-550.htm

Ordered on November 9 at 12:00 PM MST~
Shipped out on November 10 at 1:40 PM MST~
Delivered on within 3-4 days cant remember

Update:
Jacob over at ARM called me up and told me that these are slip ons, so they won’t fit early ‘11 550i’s, however, he did make up a suggestion saying “All that is required is to cut off the slip-on style flange and add the oem style flange.” so I’ll still be putting these on, however, the installation process will just be a bit different


UPDATE:
They’re in! The sound is INSANE and whistles are definitely there. Honestly, for some of you, it might be too loud, but if you want a roaring v8, then these are pretty good for the price.

Install took about 5-6 hours, including cutting and welding to fit early 2011 version

Install wasn’t too bad. Hardest part honestly was getting them to fit after cutting and welding

Video later tonight

Downpipes:

I am straight piped with an x. Looking to get rid of the x and just go completely straight very soon.

following - interested to know the quality on these

You will throw a CEL for sure. No way around out. Which is a deal breaker for me. Get something to clear the warning or put black tape over the light! I just ordered their intake so I'm pretty excited for more engine noise!

Let us know the cost for getting them installed! I'm hunting for a pair of used m5 cats.

Left an update!

They’re installed and WOW.

No CEL yet, but it might pop up.

Fully straight with an x pipe

So how is the smell? This is THE only reason I am hesitant to install DPs
Any way to weld in somewhere in the middle a universal cats to catch that horrid smell?

I've seen some suggestions that you can install a high flow universal cat after the DPs. You would still have a CEL, I think.

If I install DPs I'm going to flash/tune it anyway (no gains without tune IMHO) and that will hopefully take care of CEL.
Installing a high-flow universal cats after DPs is an interesting idea, BUT will it catch smell? I'm not so sure
Anyone has any experience or links about it?

[Simple5]

You will get a CEL, if you do a search people have tried everything. The only way of removing the CEL is with an o2 sim or by tuning (JB4 or Flash).. buy a cheap obd 2 scanner on eBay if you don't have either and clear the code.

CEL came on.

Trying to get a video asap

What was the cost of installation?

[535_BiTurbo]

Any tried the 02 sensor spark plug non fouler trick to eliminate the check engine light? It has worked on my Vette and Escalade in the past.

Well, on the mechanic side, 0$ if you’re using oem flanges (if you’re cutting and welding rather than slipping on)

But if you’re paying a mechanic they prob wouldn’t take less than $500 to cut and weld and install. I paid cheaper than that, but every other mechanic tried charging me $500

Had my buddy do it who is certified as well for a lot cheaper

If you were to just pay a shop to slip them on, it’d prob be like 100-250$ Or just do it yourself

Honestly never heard of it or tried it. Had a 370z before this and never had the need to do any of that to eliminate a light. I’d just delete the code

It won't work. A guy tried a while ago along with mini-cats. That wad also a no go.
