Will be doing the 428>435 exhaust conversion shortly and I need to buy a M-Performance rear diffuser. There are an overwhelming amount on eBay. All appear to be pretty much the same price. What is the best non-OEM one? Thanks in advance!

Here are some of the ones I'm looking at:

1)

I bought #1 - he accepted a best offer price of 225 shipped.

Fitment was spot on, except the 2 outermost bolt holes don't line up. Doesn't appear to affect anything. The mesh is metal and flimsy, might upgrade it at some point. Behind the passenger mesh - my car is AW - a section of painted bodywork shows up. (I used gorilla tape to hide it.)

Shined up / protected with Adam's VRT, it looks great. Would never think it wasn't OEM.

I'm looking at the same one. Can you please post pictures? So what did you do about the outer bolts not lining up?

My guess is that you are looking at the exact same product produced in the same factory in Taiwan. I'd go for #1 since you can get it for $25 less than #2 and #3.

Since this is made of plastic could the outer most holes have been drilled out a bit to make them line up or were they so far off that it couldnt be fixed?

[zman1237]

I just ordered #1. $225. Interested to see what you did to fix the hole alignment.

This same company is offering a nice deal if you get both the front lip and rear diffuser $500 for both. You end up saving $100 versus buying each one separately. I may pull the trigger on this.

Don't do it tboooe. You can get both items for cheaper and don't have to buy them as a package from this site.

$249.95 for front lip and $169.95 for diffuser.

Sorry zman. I just found this a few minutes ago.

[zman1237]

You think that one for $169 of similar quality? If so, I'll see if I can get my previous order canceled...

I believe it comes from the exact same manufacturer. Although I've never ordered from Bavarian Autosport before, I know they have been around for years and would trust them more than an ebay seller. Bav Auto charges shipping so it's probably only about $20 less than what you paid with ebay. If you can't cancel your order with ebay seller, don't let it ruin your day. You still paid less than half for an OEM diffuser.

[zman1237]

Yeah with shipping it would be $188. Still worth asking about cancelation.

Yeah I really wonder about the quality. That's a big price difference.

[zman1237]

Great news! So I emailed the eBay seller #1 and informed him about the price difference, and he matched the price by refunding me the difference. Excellent seller and I would recommend him to anyone. I just received the part and it looks perfect. Absolutely no complaints. Very happy so far. Now I just need to get everything installed!

I didn't do anything per se - i just left those bolts off. it's rock solid without them, so i didn't bother redrilling the holes, etc.

Wow you got that part fast!!!!

If you do not mind, could post pics of the misalignment of the last screw hole? I am curious if it can be easily fixed. My OCD nature would never allow these outside screws to be not installed.

Damn for 250 I might get the lip.

I wasn't planning on getting one but kinda hard not to at that price.

I am getting it for sure after I finish the paint and install of the diffuser. I believe Biimian sells the same one for $295 that another member purchased. Fit looked good.

Glad it all worked out zman. Can you post pic before it gets installed?

[zman1237]

I won't be able to post pics until later this week but I will make sure to do so then.

[n00bim2015]

so after all the time and research and headaches would you say aftermarket replica vs OEM diffuser for a recommendation?

thnx all

[zman1237]

Here are some pictures. Just waiting to pick up a fellow member's exhaust and I'll start the install.
