You may well be inspiring me for my next mod

UPDATE: 05-02-15 - installed Horizon LEDs for rear turn signal and outer brake light.

Install was easy and the lights worked as expected. I did the usual coding to get rid of the cold/warm bulb check and to enable LED. One thing I noticed is how immediate the LEDs turn on and off. With the bulbs by comparison you see how it gradually gets to its brightest level as well as how its brightness gradually fades. Though I knew this is how LEDs and bulbs work, it was cool to see the difference.

I got the 50W rear turn signals so I worried that it would be too bright but it turned out to be just as bright as the stock bulbs. The outer brake light is just a little bit less bright than stock. I think this is because of how the LED bulb is constructed with the projector lens. The stock bulbs sends light in all directions making it seem brighter but the LED projector focuses more light directly backwards. Below are some before and after videos at night. You cant really tell much difference. I will make another video in daytime today.





Before LEDs

After LEDs

The instant on-off of the LED's looks great, but I really would like to see how they look in the day time, and for you the California sun, before I go with them.

If you can get any pics on the sun, or share your thoughts on them in the daylight it would be much appreciated tboooe

Yup, will do so today! Stay tuned.

Here is a video of the LED brake lights during the day. They do not look very bright but its just as bright as the upper brake lights. I will try another video later, perhaps using something better than my cell phone.

Now you're making me feel like I want to add that to my mod list. I was thinking about reverse lights as well. Looking good!

Here is a video of the Horizon brake and turn signal LEDs in direct sunlight. In this video, the sun is at my back shining directly at the rear of the car. My cell phone is capturing a flicker of the brake LEDs but I assure you that you cant see the flicker. The turn signals are plenty bright and the brake lights are just as bright as the top brake bar. I would love to see other videos of people using LEDs for the outer brake light.

Yeah, I am waiting on the reverse lights. According to Horizon they should be available soon. Do you have any issue with the reverse camera at night with your Alpine White car? For me its utterless useless. I am thinking of covering the lower portion of the camera so that it does not get the reflection from the white bumper. The other hope is that the LED reverse lights are much brighter than the stock lights which could help balance out what the camera is seeing so more of the background is displayed instead of being washed out by the bright reflection of the bumper.

Yep. It's terrible. I'm hoping as well that brighter reverse lights will help. I'll wait for your verdict

UPDATE: 10-02-15 - Dual exhaust conversion

I finally got around to installing the 335/435 exhaust to my 428i. Based on glowing reviews, I drove the 1.5hrs from my house to Mike's Mufflers in El Monte. Let me say first that I HIGHLY recommend this shop for anyone looking for any kind of exhaust work. They are very professional and conscientious. The technician who worked on my car, took his time, answered all my questions, and was clearly very interested in doing a good job and making sure I was happy. Overall I am very very happy with this mod. I think the dual exhaust looks fantastic, especially with the Cyba tips.

Installation:
As others have mentioned this is not a straight swap as some custom work needed to be done. Any decent muffler shop can do it though. The first thing I noticed is that the 428i muffler is much larger than the 335/435 muffler which didnt present a problem. I was just surprised to see how much bigger the 428i muffler was. The muffler pipe also does not line up with the the existing pipe on the car. It is too far towards the center of the car compared to the existing pipe. The technician had to cut off the pipe at the muffler and fabricated a new one made of two pieces welded together. This new piece was then mated to my car using the OEM muffler clamp.

Another custom task was the need to move the existing exhaust tip locating pins back and cut the outlet pipe in front of the locating pin. I did this because I am using Cyba's 3.5" clamp on exhaust tip which sticks out a bit more and shows more of the outlet pipe.

The final custom task was a new exhaust hanger piece on the right side. The original hangar was to short and did not fit all the way into the rubber hangar support so the technician made a longer one that fit completely through the support piece. I dont think this piece was really necessary but it showed how careful Mike's Muffler is.

The sound:
I did this mod purely for looks so I was not so worried about the sound. However, there is indeed a difference in sound so I thought I would comment here. There is definitely a throatier sound than compared to the stock 428i exhaust. I can hear more of the exhaust in the cabin as well. Overall, I just hear more of the exhaust all time which but the sound is nowhere near loud as one would expect from the stock muffler. There is slight drone between 40-60mph and 1500-2000 rpm in ECON mode. Again this drone is very slight and nothing that would annoy me. In Sport mode there is no drone as the rpms do not dip below 2000.

Here are some pics:

My car at Mike's Muffler:




The locating pin moved back 1" after cutting off the excess pipe:



How the Cyba tip fit before and after moving the locating pin back 1" and cutting off the extra length of pipe:



The custom pipe mated to my car:


The custom exhaust hangar:


The end result. I noticed the right exhaust tip is lower than the left by 1/8", otherwise the alignment is perfect. I am going to let it settle a bit and then adjust it.

Interesting exhaust hanger extension, mine just sorta sits in there, the metal goes about halfway thru and doesn't even pop out the other end but I don't think it matters because even if I push the muffler it won't budge at all so I'm not too worried.

Looking good tboooe! Can't wait to hear it

Yea this custom piece was not necessary to install the muffler, its more to allow for fine tuning of the exhaust tip position.

Oh its no big deal, it wont sound like your MPE! BTW, the dudes at the shop remembered you.

[XenaBimmer]

Looks awesome!

[smithf80]

Love it tho, so now we both are going to order the MPerf diffusor and front lip, so basically we will have the same car in different colors, LOL!

I am still undecided on the front lip. Don't feel like spending over $1k on a carbon piece just to paint half of it though it looks awesome. I am going to do the m4 side sills first. I'm also hoping a m4 style trunk spoiler becomes available for the f36. Coil overs are also on my this year.

I am waiting for the cost to come down as well or just get an eBay one.

Ahh thats right, the trunk is different on the F36 I guess. Some of the eBay items list compatibly for F32 and F36 tho but I'm not 100% sure if I would trust those.

Trunk spoiler is DEFINITELY on my list to get in the coming months.

Haha really? I guess it's not too hard to remember the BMWs that visit the shop.

Also I agree with the front lip not being worth it. That's why I went with Autotecknic since it looked identical, heard good things, and was cheaper. Still though to spend a lot only to have it get scratched..but it looks good. You just gotta see which you care about more

Awesome thread. Wish I lived in SoCal. Your cars stay so clean...

It also helps that dont let me kids eat, drink, breath, or touch my car with any body part except their rear ends and backs.

[tboooe]

Got more goodies...

The color does not quite seem right..we will see how its looks after I install this weekend.

[Jimminez]

Missed the exhaust install. They did a great job. Looks good.
I can't wait for mine.
