I'm looking for a carbon fiber performance diffuser for my E90 328i (single exit exhaust). I'm about to buy the M-Tech Bumper, so I want to get a Carbon Fiber performance diffuser with it.

From people who have had experience with the RW Carbon Diffusers and the Duke Dynamics Diffuser, which one do you guys prefer?


Here are the 2:

RW Carbon Carbon Fiber Diffuser

Duke Dynamics Carbon Fiber Diffuser

may be look for a single exhaust hole diffuser? car will look awful if you have the 335i diffuser

I've read many times on the forum that DD diffusers are hit or miss; some fitment issues. Also because they are made to order, sometimes they can take 4-8 weeks to receive one.


The RW one is for 335i. As for the company, I have personally dealt with RW when I purchased and picked up my Hamann lip. Nice people. Good products. Picked up a couple days after messaging Eric.
