CSL Diffuser options

[ej257]

I've been looking to pick a CSL rear diffuser and was planning to go with Mile End Composites but it looks like he's unable to continue to produce these/NLA (based on his most recent IG comment).

Other than OEM, what other options has everyone been satisfied with, fitment/quality wise?

Happybuyitnow168 aka amoeba wings out of Taiwan iirc.

Damn, these were like $270 just a while ago. Still, outside of OE or MileEnd, this is as good/cheap as it gets imo.

^ that's 2x2, here's 1x1 at same price:

Wait for a used Mile End or VCSL one.

Yes, Mile End composites had the following to say just a week ago (to me via email): Unfortunately they are no longer available at the moment. We no longer have a mold to create it, as our mold has reached the end of its lifespan. We are hoping to recreate a new mold sometime this summer if we can get a hold of another OE diffuser. Sorry about that. Stay safe!

Here's what Ana at Karbonius had to say back in Oct 2019: Regarding with diffuser, sorry, we do not have in catalogue. There was a problem with mould and we decided not to manufacture it, at least at the moment. We are now working in an online shop and our website is not being updated

I bought a SG piece and it was/is fine. I bought 2x2 regular weave (they couldn't do it in pre-preg). I opted for paint match and it was spot-on. I had to shave down the top from the inside to fit well enough into the bumper. The bottom fastening hole were a little off. It looks perfectly fine from the outside. With 15% discount I paid a tad over $525 inclusive of the $180 paint match. I only cared to check with Mile End recently because I had a new rear OEM bumper and wanted to put the best possible piece on, since I was going to the effort of repainting. Now I'll keep what I have.

+1. Got one of those a few months back. Quality, fitment and paint match are all pretty good, especially for the price.

And yeah they really upped the price on those. Got mine for $298 + tax and shipping. Total came to $318.

Here's a couple pics of fitment and paint match:

i got one years back from Tekarbon (which is prob the same as the happybuyitnow on ebay) Fitment is great and i kind of like the metal tab used to install over the factory clips. Makes removing them effortless & less prone to damaging.

if you want the highest quality, wait for mile end or karbonius. If you want good-enough quality, just go with Happybuyitnow168

As picky as I am, these diffusers are the least I’m worried about. Even the cheap ones do just fine for me

Exactly. We're not talking the boot or airbox or something really important.

The messy 2x2 weave on the exposed part of the SG piece that came on my car eventually irritated me enough to replace it with a 1x1 Mile End piece. Really cheapened the whole look and I couldn’t unsee it. How is the weave on the happybuyitnow ones?

Not Karbonius-level, but pretty good. This is the best pic I could find:

Hard to tell but certainly looks better than SG 👍

[heinzboehmer]

Yeah picture's pretty bad. I can grab a better one next time I go out to the garage.

I am tempted to get one of the happybuyitnow pieces but worry it will touch by double walled SCZA muffler tips, just eyeballing my setup and pictures of CSL style diffusers looks a bit tight.

Anyone with the larger diameter tips on a SCZA muffler running one of these diffusers?

[Tbonem3]

I have 82mm (OD) SGT tips and they didn't touch.
