Choosing an Exhaust Diffuser for the F32

It's finally that time to choose an exhaust diffuser. I'm fairly certain that I want to go with quad tips. I plan on getting the CG precision or meistershaft exhaust. So who has a quad diffuser here? I'm looking for one with good fitment for an F32. If I go with a basic flat black diffuser I'd like to get one I can paint to match body color, while leaving the center flat back. I'm also considering carbon fiber, even if its not real.

Need some suggestions! My main concern is fitment.

I got one, but this is part of my complete Bastuck quad tip exhaust. Never tried other brands. Depends on the diameter of the tips, if you would install 2x2x90mm or smaller you're be able to cut out the installed diffusor. Afaik Supersprint has the smallest tips.

Ebay has so many diffusers, its impossible to choose. Also, what are the thoughts on fake cabron pieces? I really want a carbon diffuser simply because I haven't had one yet. Is RW Carbon real CF?

I still am not sure if im going quad or dual tips at this point. I really wanted the CG exhaust but I can't contact them.

RW is real CF but be warned if you would buy your diffusor before make your decision which exhaust to buy...then the diffusor would maybe not fit.

If i decided to do a RW diffuser, what I then also need to buy the trunk spoiler and mirrors from RW if i wanted them? I am asking because I would want the carbon patterns to match. Is this true?

Depends on your taste and the size of your moneybag
I'd bought my CF spoiler and mirror caps via aliexpress and be totally pleased with them. Thus I got at my quad tips an outer diameter with 4", a normal diffusor would not fit because the standard tips have normally a dia. with approximately 3".

I should probably buy the exhaust first. Not having good luck contacting cg about their setup.
What other setups besides cg, meister and army have a valve controller?

Correct, this is what it looks like with 4" quad tips.

I ordered this diffuser for my 32. Fitment is spot on, for the awe quad. Unfortunately, I don't have it completed to show you as awe shipped my exhaust without midpipe so now I'm waiting on that to arrive.

Be aware about purchasing from RW, have heard the fitment isn't the greatest. All I've heard, not bashing on them

RW Carbon has a CF and poly rear diffuser. The CF model has the ridging between the exhaust outlets, the mesh cutout, and it's $599. They have a poly piece too that looks good and is $280.

Ikonsport's is CF, no ridges, has mesh cutouts, and is $450. good price

Mach 5's is $699, again CF, with 2 ridges and no mesh cutout.

I saw a CF model for $1,400 US and don't remember the manufacturer. I'm sure it's a nice piece, but too much for me.

Rieger's ABS-simulated carbon is, IMHO, kinda cheesy, but their gloss black quad tip diffuser looks good and the price is right.

For the CF pieces, I would assume, although I may be totally wrong, you will need to manipulate the bumper to get the CF diffusers to fit.

Laying CF is a lot harder than one would think. I have tried small projects for parts on my race bike and it gave me a new respect for how you would design and lay carbon, and when you're dealing with long curves, how hard it actually is to get it perfect, especially a final product that needs to fit into another piece. The ridges take time so because I prefer the ridges as it looks more like a diffuser looks, I can appreciate a piece with ridges. The bumper needs to come off (I have not done it yet) so just assume you'll need someone to help you manipulate the piece into the bumper.

Here's a follow up with it installed. Not 100% sold on the look, it sits up about half inch from the bumper

Front splitters from RW not great fitment. Side skirt extensions perfect fit.
If you go quad and have comfort access the install can mess up your comfort access.

Aliexpress - stay away from them. Bought mirror caps and side gills, very poor quality. The side skirt extensions COMPLETELY crap. Absolutely no figment. And the parts came damaged and quality was crap - edges were ragged and uneven. I tried working with them for refund but they locked me into "return product for refund". I wasn't going to pay another 90 for shipping back crap. My cc company is fighting it. Would never buy from aliexpress again.

I would never buy from Ali either. Also are you saying all quad diffusors can mess up comfort access? Also how does it interfere with it?

I may just go for a m performance rpelica quad that I can paint estoril blue and leave center matte. However, this depends on whether the comfort trunk access can be retained. I need to figure out if all quad diffusors eliminate it. I read something about this but that was only on the F80s.

Yes. Good point. Didn't think it would be designed to foul that up, but you never do know do you

Quad requires moving the housing that works the comfort access. This is what owner from RW told me when I told him I was thinking of doing a quad. I have no reason to doubt him and he wasn't trying to push me a deal. They've been straight up. Glad I heard that b4 I dropped more $ for another mod. Happy with my Remus.

This is the crap side skirt from aliexpress. The edges were warped. The other side came with crack from the box.

Was first thinking of a Rieger diffusor too, but they'd told me that the cut outs are limited for 3" tips. Hence I got 4" I had to buy the OEM ones from Bastuck, but Im not totally pleased with the fitment and quality. Next time I have to remove the diffusor and stick it proper back into its bumper sittings. From any reason it has slipped out onto the right side.
What kinda exhaust you've got?

Cant confirm this. Bought meanwhile mirror caps, interior stuff and more, never failed, fair quality and good prices.
