I want something that will not lose low end torque abut little more quiet then "west" and "socalE39" setup would this be a good setup? from OEM cat - OEM resonator - Mangaflow X muffler #11385 - OEM center resonator - Mangapack # 10425 on each side to dual tips on each side?
I have a 08 550i
I have a 08 550i
This was my first setup, and it was very loud at the low rpms (1800-2200) or when the engine is tugging (assuming you have the v8). That is called droning. It is stock sound when you go above 3500 rpm. It idles quite loud too with the AC on and a hot system.
Sound level is relative to everyone unless you have db meter. But I prefer not to get into technicals. With the magnaflow, it sound intoxicating at first, but it will get old quick. If the stock sound is rated at a 2, I would rate the the magnaflow to be a 6-7 inside the car cabin (at the low rpm). I got rid of my magnaflow and purchase a pair of turbo tubes from Jones Exhaust. These are channeled (snaking the exhaust gas inside the tube), and it will allow for backpressure, but size is also smaller (1.75"). All the while, it reduces the sound by 3/4 of the magnaflow.
Think about it, if the stocks widest pipe is 3" (after the center resonator Y into a left side 3" pipe, two 1.75" is still more flow than stock, and the channeling plus x-pipe (upstream) will give it some backpressure assumingly equally the stock mufflers.

Got one of the videos...removed a lot of scenes, but still made like 5 or 6 appearances.
http://www.youtube.com/watch?v=VIGDrg4vgiU
Got a front and rear at 1:05...few more throughout.
I'm also in the video with a couple of my boys, I'm the guy in the black hat white shirt black jacket, next to my cousin in the blue dodgers jacket.
I'm a little unimpressed, they took way more footage of the car but edited quite a bit. Said they would use the footage elsewhere. Oh wells....

Thanks for this write up!
I just ordered the same parts, (minus all hangers) and set up install on Tuesday next week. I'll add more pics and video when it's done.
Parts plus labor will be just under $700.
Edit: I actually got a different set of tips, Magnaflow 35168, but virtually identical. 2.25" in, dual 3" out. (any bigger and it won't fit well under the openings)

I get a fair amount of mail from you guys asking for parts and install information because the photo links were broken from earlier in this thread. Here is what I was able to get a hold of. Hope this helps.
Here are the parts you will want to obtain:
Mufflers will look like this:
Attachment 118755
These photos aren't the best, but you'll want to hack the existing exhaust off just after the first set of resonators then weld on some extensions:
Attachment 118756
Install the 11385:
Attachment 118757
Here is another view after the 11385 has been installed. Notice the position of the existing hanger:
Attachment 118758
The additional hanger you ordered will be placed here (red circle):
Attachment 118759
Routing for the 10425's will look like this when you're done:
Attachment 118760
Left and Right pipes to the tips will be routed similar to this:
Attachment 118761
Attachment 118762

What is it with this backpressure talk. You don't need back pressure in a system. You need to match the velocity with the diameter so the gases can expel quicker. You DO NOT want backpressure. The whole point is to get ZERO backpressure. If you have backpressure, you will lose HP, if your piping is too big you will also lose HP.

Did you think about bumping it up to 2.5" piping or has the 2.25" given you gains.
