Zeus Lightning says:

No carbon fiber?

S D says:

what exhaust is this???

Ben Sellick says:

Can I put this on without an M sport bumper?

Matt says:

A body shop quoted me $1000 for this. Thanks for this video.

Ben Hasson says:

Great video as always. Big Fan. Would this diffuser fit a non M-Sport 335?

Joe Herbert says:

Do you need the m sport style bumper for this to work, I have a 2017 330I without m sport package?

Jeff W says:

What exhaust is this? Is everything stock except for the muffler?

Joseph Gadawski says:

Looks awesome!! Will it fit 2013 335i Xdrive Luxury? I’ve installed the AWE Tuning Touring Cat Back exhaust and now a proper diffuser will match the aggression of the sound. Your videos are the best DYI out there. Look forward to your response.

C15 0001229684 says:

This is way harder than the guide looks, or I got a bad mold. The clips by the reflectors are impossible to put in, even with two people. I screwed it in with those 2 unclipped and it looks poor.

Also, the part on removing the original diffuser is not really optimal. Start at the very end and pull out, not by the tailpipes. I tried doing what he does in the video for 10 minutes with absolutely no give, then tried started at the end and it came off easy.

C R says:

are those the 3.5 inch tips or 4 inch exhaust tips?

Chris says:

@kiesmotorsports will this work with 2018 340i? any info is appreciated

O says:

What tool did you use to remove those 8mm? Thanks in advance!

Hong Thach says:

Hello Bryan I just bought a F30 2013 about a month now. I'm really interested in get a quad exhaust. That would be nice with that diffuser. I will be making a channel soon. I really appreciate all you video instruction. Thank you.

Daniel Park says:

I know it’s been a year but maybe you’ll see this. Will the diffuser fit a 328i with custom exhaust to make it look like a 335i?

Emrah Bekir says:

bro, I got a quick question, will a diffuser off of a 335i fit a 328i? I got a 328i GT M Sport and wanting to do dual exhaust… can't really find much for it since it's a GT M Sport

Rolling Cloud says:

is it painted? mat black?

Ismael Rodrigo says:

Wich diameter are your tips?

That F30 says:

bless your soul just used the coupon and now waiting for my diffuser!

Jeff Ladd says:

Not bad for $195 bucks. If only proautomotion’s diffuser for the F10 535 was the same price (not $895!)

Mats Vas says:

How many horses does it add bro

Kaelthos says:

Is there a similar diffuser for the either 320i/330i or 420i/430i?

Drew says:

I couldn’t finish the video because of your left tip omg !!! Fix it pls ! Lmao

Mauricio Browne says:

Hey man, I don't think I have commented yet on your videos but I am always watching them. Just thought I'd say thanks for all the videos, I'm sure all of us f30 owners appreciate it!

Alfredo Espejel says:

Hello from Mexico City

karieltheone says:

Do they come in carbon fiber?

tlbern 77 says:

As always, excellent video. Car is coming out very nice.

BMW F30 owner says:

What exhaust pipe you got there?

BMW fan says:

Looks much better. I just received smoked reflectors today to replace on my car. Its a 435 msport coupe. Any pointers in replacing them? There is very little room behind my bumper (unlike yours). The silver heat shield is behind the rear bumper and in the way. Thanks
