LOL. What type of diffusor did you get? Did you get a quad CF diffusor?? Thats what I was thinking about.

I was also looking into a Reiger diffusor. Basically half the cost and manufactured in Germany supposedly.

What do you think of this one? Half the price of duke dynamics and manufactured in Germany supposedly. Also, I saw a thread with someone with a Reiger. Never heard of this brand till now

Idk I've never seen that before. And it says "carbon look" so it might not be rep carbon fiber

Hey hey! Actually, it was just a regular aero type diffuser bumper. Thing had gaps bigger than Octomom's lady parts...

Can't go wrong with ECS. Maybe my experience was exceptional, but checking the forums, I don't think that's the case

Update on my diffuser. The shop who is installing my diffuser along with the quad tips said they got the diffuser on, he said the clips were a little too big but they got it on after messing with it a little

The DD/BK diffuser I have is very similar to this quad in question except mine is single exit only as I have a 328i.

[Blindside_137]

Here's my story. I've shared it tons of times but I don't mind supporting DD when I can.

I ordered a diffuser of Duke Dynamics but through the famous west coast shop LTMW. I waited 4 months for it and was constantly being given the run around (because I think DD was truthfully backed up and busy, and was giving LTMW the run around)

Finally the diffuser shows up and it's the wrong one. It was one of the finned diffusers and I wanted the Performance style diffuser. I ship it back and LTMW gets me the one I ordered promptly. I finally am all scheduled to change my bumper to the m sport from JGmods, mount the DD diffuser to it, then convert my 328 exhaust to the 335 style. The performance style diffuser was only available in 335 style quad or dual, and I preferred the dual exhaust.

I get my car from the body shop after a few days and it looks better than imaginable. The next day, I'm rear ended at a stop light. I have a 9k insurance estimate on repairs and it turns out to be more. After deciding it won't be totaled we move forward with repairs. I get another m sport bumper from JG mods but he doesn't really help much with the diffuser. So I say what the heck, let me email Duke Dynamics directly and see what they do.

I talked with Chris over email and he was phenomenal. Quick responses, showed my pictures of what diffuser they had in stock. It was exactly what I had before, but the carbon fiber weave was 2x2 instead of the 1x1 I had previously. I much preferred the 2x2 weave and preferred a white logo but didn't think the red logo would be so bad. Turns out the red logo is a nice little touch that I love. They even honored the lower price that I had paid LTMW. It was supposed to be 650 or something I think.

Anyway, it was shipped out immediately and arrived after a week. I couldn't have asked for a better fitment and experience from DD.

Thank you for the review!
I called DD this week. Their lead time is 4 weeks....I've heard stories going both ways now.

I want their quad diffuser with fins.
I'm mainly concerned with fitment. I don't want to trim anything. Just want to do a simple pop off and pop on touch. I want to buy off a forum member if that's possible but it's difficult to do so. These are in such high demand. I wish they kept a massive stock...they should

[Blindside_137]

No problem! I was just lucky they had one in stock. I would just see if they would make what you want, but you wait to pay until it's in house and ready to move out. Can't hurt to ask.

I believe they are not scammers just very busy guys. They have shut down their factory in China and production is now in Vancouver so that they can keep an eye on quality. But they are backed up and they told me anyone wanting a refund should go through Paypal. Their products are good quality but you will have to be reeeeally patient if you want their stuff.*They also don't spend much time responding to emails which I told them makes people mad but they are just too busy working on production.

What do you think of these options?? Idk about fitment
Saves money from DD's $700 diffuser...

Thank you! And no I was getting msport put on so I gave the shop the diffuser and tips and they did it. Yes I have the BMW pe with Cyba quad tips. Also if you end up getting the duke dynamics diffuser, I recommend getting the one that has a 22cm opening because I read the 18cm one touches the exhaust sometimes with the Remus exhaust.
