CSL Diffuser options

[JayReplay]

DMC diffuser looks good in terms of fit and CF weave quality. I may give it a try (slightly cheaper than the HBIN vans euromotorsport ebay options as well).

Mpartsworldwide by me (the e46 dismantler), sells DMC ones (basically the same as the HBIN ones)....i can confirm they fit like all the other ones using the metal tab design, since my cousin has one on his E46. Keep in mind its on 2X2 option though

This is Mparts' ebay store. On the DMC site, the diffusers look to be $100 more.

for some reason i'm feeling the 1x1 weave more than the 2x2. Now I wished my Karb airbox was 1x1.

Nah you did the right thing with 2x2 for the airbox.

I know you guys have mentioned the waviness in the diffusers, but I’ve stared at my knock off and can’t seem to spot it? Is it really that noticeable?

Don't go looking for it .. there are far better things to be OCD about and far better things to waste car money on than a new diffuser lol.

LOL its def gonna be one of those thing i can't un-see once i find it.

Are there any CSL diffusers that aren't wavy that aren't OE, Vorsteiner or Mile End?

That's my biggest irk.

This is exactly why I ditched the ugly wavy 2x2 SG one that came on my car as soon as Mile End started selling his back in the day. Shame he disappeared.

I remember I got a couple factory diffusers in the mid 2000s and I was appalled at the then $800ish price tag I got them for.

Maybe the $2k price will look cheap in 10 years...

I looked for a long time. No clue if there is. I may swap this thing out if it bugs me after paint. Buy cheap, buy again. But I sure as hell wasn't gonna pay OEM price for this piece. OEM CSL makes sense for some pieces, but $2k for that piece... for me, doesn't compute.

Epoustouflant has a decent looking one from Rene I believe. I may go that route eventually, even if only because the metal tabs bug the crap out me on the happysuckafool piece. I mean seriously... oversized paperclips is what they gave us to work with?

BTW, I saw someone mentioned "would be nice if Karbonius started making these" or something like that. I agree and asked Karb and they currently have no plans to make one.

Going to bring my diffuser in for paint in the next couple of weeks. Does anybody have any solid reference photos of how an OE CSL diffuser should be painted? Looking at the HBN painted diffusers looks like a little too much carbon was left exposed
