Hey guys,

Before anyone get it's panties in a bunch because they haven't gotten there DP, i ordered mine in September when AR was just starting to try fitments with Matt@cambertoe because they didn't have a local car.....and i even bought one from the local that took his car to AR for the actual fitment( hint hint... i have another DP that I'm going to be selling =) )
And again, my car is a 2011 135i with the DCT (dual clutch trans)

Anyway, i got my AR downpipe last monday but i was out of town so i couldn't get to put it in till Wednesday. To be honest, the DP was SO EASY to install it took me 1 hour start to finish on a lift and proper tools, including the time to wrap the pipe with heat wrap. I didn't bother doing a right up on the install because if you can't easily do the install then you shouldn't work on your car at all, there's plenty of space in there. It would take longer to do a right up then to do the install, it's that easy.
The DP is Flawless, fitment is perfect and the AR quality is definitely there from the flanges, the welds to the o2 sensor bungs...just perfect!
The OEM pipe is very heavy because it's got 2 cats in it, the first has to be at least 600 cell and the second 400 cell. it also necks down allot right after the turbo as you can see in the pics . The AR on the other hand is very light and it doesn't neck down like the OEM pipe and it also has mounting brackets for the OEM mounts so everything in nice and kosher.

Now, for the power. As soon as i pulled out of the garage i noticed the throttle response was much sharper and the engine felt more quick to rev and of course, the sound is just sick!. The DP definitely added HP EVERY WERE in the power band, from low RPM all the way to red line and the power doesn't die out as sharply past 6K RPM, instead the car now feels powerfull till 65-6600 RPM and that is a very welcomed feeling because my last car was a 6XX AWHP Evo 8 that i used to rev to 9K RPM all the time... and the car rev's faster so now the Performance steering wheel that i put in the car is really usefull with the built in shift lights.
If you ask anyone that knows me personally they'll tell you that I'm a wheel and exhaust whore, and this car is no exception. I've got 3 different exhaust setups(Berk street catback/ resonated midpipes and muffler axelback, Active Autowerks/stockmidpipes, Riss Racing catback)(well 2 because i just sold my Riss catback today) as well as 2 wheel setups so i tried them both with the AR DP to see witch one i liked better before i sold the other one. I liked the Active setup better and thats what i left on the car.

So were are some videos that i took with my IPhone 3 so that everyone get's a chance to hear what there car would sound with the AR catless DP. Also, note that on the 135i with the N55 engine the midpipes don't have cats in them so keep that in mind when listening to the videos. I also did do 2 flyby videos by request( you can hear the DCT in action to!) and feel free to watch my other videos under my youtube user name =)










Berk setup:


Active setup:

This is AR DP + stock N55 midpipes and Active Autowerks axelback (muffler delete)

This is AR DP + Berk full catback (resonated midpipes+muffler axelback)

Flyby2

One last thing, I've seen that the BMW community doesn't seem to believe in o2 sensor spacers so i gave it a shot because i found out that the PROcede doesn't have the catless DP code in the CANclear memory(Shiv already has the code so they are going to added to the CANclear memory in the next couple of weeks) so it won't auto-erase the CEL. I've driven about 40-50 miles mostly highway but also some city as well as aggressive driving and no light since i did the spacer mod, when it would have come one by now before.... and i'll let you guys know if this changes.
What i did is i used 2 spark plug non-faulers and drilled one of them so that the sensor would fit in the first one only, here's some pics of the finished product:

wow! that first video...omg...that car sounds ridiculous.

[black e]

I know, right!?! you can hear the turbo and everything with that setup!

[lyndon_h]

Incredible. That thing sounds angry

[htt760]

I like the berk setup better for dd... but muffler delete equals race!

[FrankiE90]

gawd dayum, dat's sik.

[adrianBMW99]

Both setups sound crazy! I personally would prefer the second one as it seems a little more fitting for daily driving but good job testing both out either way!

You are like one of the first with N55 downpipe, I just dont understand why you didn't take any pics of it installed on the car! Thanks for the video but some pics of them installing it and after installation would have made this thread perfect....

I can't decide what I want to do first this or get an exhaust system ... That sounds just nasty .. Has this been adjusted to fit the x drive ?

[shockin330i]

Um, dp is way better than an exhaust. its cheaper and will yield way better results.

[N55 Power]

would it be possible to install with ramps?

[black e]

Yes, no problem

[htt760]

thanks for the review! wow it took that long to get your pipe?

[black e]

well, i jumped the gun when they still didn't have a fitment car....

[Bimmer This]

Looks good!
