240691 (478hp) If I were to stick with my non-M bumper, I would go with the Hamann

tiffany5 (666hp) Quote: Originally posted by dadysev Ok, the answers have probably already been answered in other threads, but I can only find partial answers that I need. I have the non-sport rear bumper on my 550i and am thinking of fitting the Msport bumper with a not too aggressive rear bumper. Question 1. Are the M5 rear bumper and M Sport rear bumper the same? Question 2. Do I need additional hardware to attach the bumper? Question 3. Is additional hardware required between the M Sport and the M5 Valence? Forgive me, I'm a bit confused.

I just installed an OEM M Sport rear bumper on my non-M Sport car and you don't need anything other than just the bumper, diffuser and a small sub-shell to attach the diffuser to. I don't know all the information here on the forums that says you have to replace the entire bumper assembly. I was lucky that the person who sold me the bumper included all the other stuff for free.

The final product will look like the all stainless steel Remus quad setup (example below). If I have the MSport 550 and just want to do a more aggressive diffuser along with M5 mufflers what would I need??

If I have the MSport 550 and just want to do a more aggressive diffuser along with M5 mufflers, what would I need? just a more aggressive diffuser. Keep in mind that carbon diffusers don't have the best fit as they are much more difficult to bend and shape into place

patryk1 (560hp) I recently installed a diffuser on my 535i and it has a quad exhaust. The exhaust actually touches the ends of the diffuser, causing it to melt. My only option is to make the pipe completely straight and cut the mufflers with new tips, but I'm not sure where I can get the pipes needed for the new tips. Everything that goes online only sells the tips and not the pipes, which I need ideas for?

ahess (694hp) Have it adjusted by a muffler repair shop

220688 (814hp) Sounds like you bought an M5 diffuser and not the MSPORT

myshit1 (426hp) No, only the exhaust comes out on both sides

Wanted123 (571hp) I recently installed a diffuser on my 535i and it has a quad exhaust. The exhaust actually touches the ends of the diffuser, causing it to melt.

ashley90 (344hp) The air conditioning was re-ventilated with UV dye two months ago and was cold, but a few weeks ago it was no longer cold again. I checked the system today and the suction hose glowed like a Christmas tree in the blue light. The adjacent heat shield was also glowing with paint near the crimped rubber section of the low pressure suction hose. A new part has been ordered. The evaporator and condenser all appear to be fine, no dye is visible in the interior vents, air conditioning drain pipes under the car, and around the radiator and condenser/dryer. I consider myself lucky. The 10-11 years of heat exposure have likely weakened the rubber section and crimp connections. The aluminum filler pipe where it is clamped to the side of the engine compartment is also subject to wear from engine vibrations, so a new part is urgently needed. Now I'm looking forward to next summer.

yellow15 (170hp) Remember to change the desiccant in the dryer. Your old desiccant is probably saturated and can no longer absorb moisture.

180886 (75hp) Does anyone have experience with these M5 rear diffusers on eBay? I'm wondering if the exhaust cutouts are center mounted similar to the OEM M5. https://www.ebay.com/itm/Rear-Diffus...Cclp%3A2334524

sexymama10 (423hp) When it comes to eBay, it's a godsend. Mine was fine, but it took some finesse to get the tabs to fit, and I had to use screws to keep the tabs from pulling out. Remember that there are two versions: M5 and MSPORT. On the M5, the exhaust openings on the diffuser will be directed further inwards, like mine. The MSPORT openings will be similar to those of a 550. When I had my masters install the muffler, they had to align it pretty accurately

sexygurl (606hp) Yes, it's easy to tell whether it's M5 specs or not. If you look at the second image with focus on the edge, you'll notice that it's pretty beefy. This shows that it is an M5 specification and is therefore designed to accept more inward muffler tips (or an M5 muffler). For example, if you look at this diffuser, you'll notice that the sides are much slimmer, suggesting it's made for the 550i and more outward-facing muffler tips (a stock or aftermarket 550i muffler). https://www.ebay.com/itm/For-BMW-5-S...AAAOSwsmdd7a7w I believe they also make these for the 535i to accommodate single muffler tips and these actually have the same beefy sides as that M5 specification. https://www.ebay.com/itm/Rear-Diffus...QAAOSwZQpf9sx8

21061981 (488hp) Thanks guys! This is my current setup. It actually looks beefier than the Msport setup. One would think that I might already be prepared for the M5 positioning?

pleasant1 (869hp) Based on the fact that the tip of your inner muffler sits directly under the tow bar cover, I would say this is definitely an M5 Spec setup. You can see in mine that the orientation of my inner muffler tip is different from the tow hook cover.

werderbremen (269hp) When I took a closer look, I just noticed that my tow hitch is disconnected, just like yours. I have to have the normal 535/550 setup. If you don't mind me asking, where did you get your diffuser? Looks really good.

halo3 (722hp) Nice looking bumper!!

danielle5 (744hp) Ah yes, from this angle it definitely looks like mine. I was a little suspicious about the slanted opening, a common design to accommodate stock trapezoidal tips on the 550i. This is what I have. I bought three in total (from all different vendors) before choosing this one because I was definitely aiming for a near-perfect fit. It's more expensive than others, but it's made in Taiwan (compared to China) and is totally worth it (at least for me). To my delight, it came in a wooden box and not just a cardboard box. The fit is 99.9% perfect. I ended up painting over the CF because I wanted the M5 look. The center is plasti-dipped as I'm not familiar with two-tone paint and wanted a matte look to give it depth. https://www.ebay.com/itm/Carbon-Fibe...72.m2749.l2649 Quote: Originally posted by Sylverlee As I was taking a closer look, I just noticed that mine isn't removed from the hitch hook, right like yours.

Mine is still CF though. Maybe I'll paint it like yours, it definitely gives it a bit more depth instead of a single color. Maybe I'll try https://www.automotivetouchup.com/ myself. I've seen videos, the 2K clear coat is the secret in my opinion.

281295 (537hp) I recently ordered this diffuser for my F10. I'll most likely paint it gloss black. I'm not a fan of this artificial carbon. I will let you know what the fit is!

nine (118hp) I sprayed the #300 base coat (also purchased from Automotivetouchup.com) with a paint gun, but 12 ounces should be more than enough for three coats. For the 2K I also only used a 12oz bottle and I think I applied four coats with it. I wanted that extra jacket to protect against the heat coming out of the muffler tips.

Usually just sand, primer, sand, primer and clear coat?

fuckevery1 (404hp) Yes, these videos helped me a lot, especially when applying the paint. Here is the general procedure I used for the diffuser and front lip if it helps: Wet sand the diffuser with #400, just enough to remove the shine from the clear coat. Wash, dry and wipe with surface preparation cloths. GLIDE a cloth over the surface to remove any dust (do not press too hard or the wax will transfer to the surface). Spray 2-3 coats of primer. Wet sand with #500. Wash, dry and wipe with surface prep wipes. SLIDE the tack cloth over the surface to remove any dust. Spray three coats of base coat. Wait 30-60 minutes and then spray 3-4 coats of 2K. Allow to fully cure for 48+ hours. There are many conflicting opinions about whether to wait 30 minutes or 1 week between base coat and 2K clear coat. I chose the former and it turned out great. There will be some orange peel left at the end, but luckily since it's white you can't notice it and I didn't even bother with the wet sanding. The orange color will NEVER come close to that of regular acrylic clear coat. The best advice I've gotten from all the videos and articles I've read is to invest as much time as possible in preparation to get good results. I literally spent 4-5 days (between work and family) preparing the diffuser before painting it. Good luck! Quote: Originally posted by Sylverlee I just wanted to follow her videos.

Run your original wheel/tire setup and this new setup information using the calculator on this website: www.willtheyfit.com. You will receive information about any impacts towards the fender and/or insert towards the suspension. You will also receive an image comparing the two setups. By the way...since we don't know the width of the 20 wheels, no one can give you a proper answer as to how they fit. We need more than offset and wheel diameter...width also plays a role in fit. The link to the above website will give you the answer to a comparison equipment if you provide all the wheel and tire specifications when comparing the two configurations.

l111111 (677hp) Simply put: M5 diffuser - specifically designed for M5 silencers that sit further in towards the center of the vehicle. M5 style diffuser - technically designed to work with 550i mufflers that sit further from the center of the vehicle. If you have an M5 muffler installed, you will need an M5 diffuser. Note that you will still need M5 brackets to fit the M5 silencers and an M5 diffuser straight. The alternative would be to have the workshop adjust the silencer mounts themselves. If you choose the second option, draw attention to it so that the tips are straight.

founder (973hp) Hi guys, I have a 2015 535 with a sunroof. I took off the headliner to attach the starlight. And to do this you have to open the sunroof to loosen a few screws that hold the headliner in place. After that I took the headliner out but wanted to close the sunroof as it was just sitting out but when I connected the controls to the sunroof it would close about 80% and then open again. Any advice? Thanks!

ferari (287hp) Could be something blocking his path. However, I think it's more likely that you'll need to reset it. I'll have to google it, but I believe you need to turn the ignition on, hold the button in the vent position, and hold it down until it's fully closed, vented, and closed again.

bobbin (25hp) The same goes for above: if the sunroof has been unplugged, it usually needs to be reset. The instructions can be found in the user manual. Some new BMW models require the engine to be running. So check your owner's manual for the sunroof reset procedure.

iBonsai (697hp) I have the same problem after a repair. I haven't tried resetting it, but all it takes to fix it is some sort of reset or code. I found that I just have to tap the button a few times once it reaches the 80 percent point and it bypasses the reopen feature.

marlen1 (883hp) Quote: Originally posted by whinojosa I have the same problem after a repair. I haven't tried resetting it yet, but all it takes to fix it is a reset or code...
