ive never gotten a answer for this but for me to put on a cf diffuser, do i need to get a new bumper too?

[_shim]

For the stock bumper, the only option for a diffuser is the hamman-style diffuser from cyba, a vender on here. To make it fit, you'd need to do a 335i-style exhaust conversion with quad tips.

If you go with an M-tech rear bumper, there are COUNTLESS options for you < this is probably easier as well, just more expensive.

does cyba still have those diffusers?

well i just pulled my car into my garage and tried to see what im dealing with, it all seems to be one piece. maybe im not seeing it? and i would love to convert it to a dual but seems the trunk space comes in the way?

Mine is a 330i and I changed the exhaust to look like a 335i. Where in NJ are you? Im in Dover NJ, you are more than welcome to stop by and take a look at it so you know what has to be done.

Well I bought the Mtech rear with the diffuser, that alone with paint and install was like $1600.
If you dont want the Mtech then you can find a stock 335i bumper with your same color and it will be much cheaper.
The exhaust work might be like $300 all together.

I did the same, basically you need to get an exhaust with 2 outlets. I used a magnaflow, installed where the stock exhaust would go and extended one outlet from the drivers side to the right side.

if you look closely, you can see the pipe hanging a little low on the right side, I need to get it adjusted but this would be the easy way to convert to dual exhaust

Now what kind of bumper did you get? Also is there any way to do it without a muffler? Cause I like the muff delete

you either need an mtech bumper with 335 diffuser, or just a stock 335 bumper. Sure, you dont need a muffler, the exhaust shop will just weld on piping to go to the left and right side.

Or just get crafty and make your own. I still dont know why a vender hasnt taken the time to make one.

I have just recently had this conversion done on my 330d msport, all i had to do is buy a 335 rear diffuser, which was a simple to swap (few clips).
The conversion is done around the trunk space, you would only need to have the trunk space removed if you wanted to have for e.g quad exhasuts more centerally.
I will be uploading some pics later

Hope this helps

Yeah but if only I had a diffuser, the bumper is just one piece

Oh ok must have missed that part, i would suggest mtech rear bumper with 335 diffuser. OEM parts you would be happy with results, if you want it look like 335 this the closes you will get to OEM

great pic, looking to do this conversion on my 320d, roughly going to cost £500 including fitting and the diffuser
