Yes, I use black sealant are-round the edge and inside,u should use the 3M tape also to pace the diffuser to the bumper frist then use sealant.

tls1212

im hesitant to do my in carbon fiber due to the fact that the diffuser needs to be flexed a lil in certain areas to fit and doing it in carbon fiber would make it pretty stiff

WaveyKat

Guys,
Finally installed my diffuser. I replaced the 3M tape Teo put on the back of the diffuser with similar 3M tape, only it's wider and felt stickier. Install went smoothly, and by the looks of it, I didn't have to use any silicone. I was originally just test fitting it, then figured I'd remove the tape backing and fully install it. Looked great, but it was lifting a little bit, and that when I decided to remove Teo's tape and use the wider stuff.

As other people mentioned in the thread, the diffuser matches up really well. My only issues are with the right side where it curves. The diffuser is a little bit short and doesn't follow the bumper cut line exactly. It's barely noticeable and no one will ever see it unless they're on their knees looking at it.

I also decided against cutting my bumper to match the diffuser's cut out on the left side (I have the single exhaust cut out). Unlike Chad's white car, which made it super noticeable, mine is Capri Blue, and I was surprised at how you can't really notice it's not cut to match the opening. The other positive is that my exhaust came OEM from the factory a little bit off center from the OEM bumper cut out. It's a bit over to the right. This ended up working out perfectly because now, the exhaust is perfectly centered with Teo's diffuser cut out.

Pics to come in a day or so, as I'm still clamping a few minor spots.

cintoman, definitely some pics to see the difference, but the question is is the exhaust tip hanging high enough.

dblock2151

Hey Frank, how do you think the Weltmeister exhaust would look with the double cut-out? I just hope it looks centered, if I do go that route.

Mr teo, whats going on with the order?? pls get back to me asap

I am interested in the C32 version...is there a difference in price? What is the price?

Hey Frank and everyone else,
Well, I was finally able to take some quick pics of the diffuser on my car. Please pardon the major dirtiness of my car. I spent most of the day detailing a friend's car while mine is all dirty.

I'd like to mention that I'm going to be removing the diffuser and re-installing it. The wider 3M tape I used still doesn't hold it in some places, so I'm going with this other 3M tape that's supposed to be much stronger. It's called 3M Acrylic Plus Tape 06384. The cool thing about this tape is that it's black versus the standard light gray 3M tape. Plus I'm also using 3M Automotive Adhesion Promoter 06396 which you apply to both surfaces prior to attaching the tape. We'll see how it goes. Should be fun trying to remove the diffuser, since it's pretty well stuck in 95% of the bumper.

Anyways, here are the pics. Like I mentioned before, I decided against cutting the rear bumper, and it's really difficult to see the mismatch unless you're on your knees looking straight into the exhaust. Thanks to my Capri Blue color. But what do you guys/gals think? Is it THAT noticeable?

The exhaust is now very close to centered within the diffuser's cutout. Plus I don't think it's hanging low.

While the diffuser is out, I'm also going to fix some of the small fitting issues. Each end of the diffuser tends to overhang (or is it underhang) past the end of the bumper on the very bottom, which is a bit noticeable from the sides (see last pic). Plus the same thing on the rest of the diffuser. I want to remove some of it so it's flush with the bottom cutout/end of the OEM bumper.

What do you all think? Suggestions. Comments. Again please pardon the appearance of the diffuser unsticking on the left side above the exhaust.


Thanks,

Bet you are glad you didn't use black sealant first time round as would be difficult to remove. When you are done with the minor jobs and happy with the fit, as i suggested in previous thread i would just use black sealant. Don't know why you want to mess around with tape as it wont stick at 100% due to the moulding not being a correct fit.

FrankW

definitely less noticeble the cutouts are different, but IMO the exhaust tip should be a little higher which with the original cutout you can't really adjust it.

tls1212

sorry for late reply due out of town! i just come back will let u guy know the pricing for the cf diffuser asap

Cintoman

Definitely glad about that. I'm sure it'll still be a bit difficult to remove it with the tape that's on now.

To be honest tudu, I'm a bit nervous about using the black sealant, when you mentioned in your thread to make sure I have a bunch of turpentine and mineral spirits. But maybe you (and anyone else that used the sealant) can help me out with some concerns I have using the sealant. Ideally, I think the sealent would work out the best, but again, I don't want to slop the stuff, get it all over my bumper, and make a total mess out of it, while still not achieving my goal of it matching the bumper cutout perfectly.

Here's my concerns:
Now that I have the black tape and adhesive promoter is coming soon, I'll probably use both the tape and the sealant. Since the tape is black, I was thinking about putting it on the leading edges of the diffuser, and then using the sealant along the inside of the diffuser. Suggestions? Should I do it this way, or install the tape more towards the inside of the diffuser and use the sealant along the outer edges. Basically, I want the top edge of the diffuser to match up exactly and tightly with the cutout line along the bumper. Right now, the diffuser is on and matches the cut line nicely. But there are some areas that the diffuser is more tightly stuck to the bumper. As such, the grey tape is not noticeable, but other areas it's not as tightly stuck, and you can see the grey tape. It's not unsticking, but just not as tight. Basically, on these areas, if I pressed my fingers to the diffuser, it would push in and fit more tightly. But when I let go, eventually, it won't be as tight. BTW, I put my expert ms paint skills to good use and threw together a quick pic showing both methods. Any suggestions on what's better/cleaner looking?

If I use the sealant on the outside edges and the tape on the inside, should I make a bead line with the sealant on the diffuser first, then press it to the bumper, or should I stick the diffuser on the bumper with the tape, then use the sealant along the edge next and press it on? Doing it either way makes me think that the sealant will be squirting out onto the bumper once the diffuser is pressed in place, which might be a bit messy to clean up. How thick of a bead line should I make?

How do you keep the diffuser pressed firmly to the bumper? My fear is that I'll put the sealant on press the diffuser in place, hold it firmly as best I can with my 2 hands, but then come back only to see that part of the diffuser moved away from the bumper, and now it's impossible to press it back in place because the sealant hardened? Suggestions? Or do I need 5 guys (10 hands) to hold this in place while the sealant hardens? About how long does it take to harden?

Sorry so many questions....



Looking at it now, I can see where you can say the exhaust is a bit lower. Raising it up won't really work without cutting the OEM cutout a bit. But I see what you mean. I'm thinking it's acceptable to me for now.

Thanks guys !!
