W204 series on this channel is a big big W . Just got my car and this guy has everything i wanna do

[@TheFlexxGarage]

Thanks. And if you know anyone with a w205 or Audi A4, I have tons of mods for those cars too.

[@kenoel23]

Nice video. Where did you purchase your quad tips from?

[@Daviddylanaronne]

Awesome bro

[@TheFlexxGarage]

Thanks!

[@ondrejryska5398]

As a W204 sedan owner I love this channel

[@TheFlexxGarage]

As a KZbin channel owner, I appreciate you watching and sticking with my videos! Make sure you share the channel with others! Thanks again.

[@luxchannelx6039]

Is it less pricey buying the tips and magnoflow yourself than getting them at the shop ???

[@HansanaWimaladharma]

Hey, a bit late but I own a 2012 W204 C250 Sedan Avantgarde and was wnodering whether I could fit a 2008-2011 c63 diffuser on it? I looked at the shape and it looks pretty similar.

[@TheFlexxGarage]

Not sure but it comes down to bumper shape. If both bumpers look the same and they both have a removal diffuser, then it’s highly likely it will fit.

[@concerts8003]

Flexx replacing old diffuser. The 2 hex screws on each side. How in the name of baby Jesus, do you remove those damn things. Are they a tri-wing hex screw?

[@TheFlexxGarage]

Not sure what you mean. Some diffusers have rivets you need to drill out. Mine apparently was replace with plastic body panel screws so it was easy for me to take off.

[@concerts8003]

@@TheFlexxGarage they were rivets. Need advice on resonators for exhaust. I dont want it to be loud, just throaty. Any advice or links on your videos?

[@swrdatsrackz]

Do you not have the c180 and c220 in the us?

[@TheFlexxGarage]

Flexx Alexander i remember reading somewhere that US only got petrol, is that true?

[@swrdatsrackz]

Flexx Alexander so no diesel?

[@TheFlexxGarage]

I don't think there's any diesel. I've never seen a c180 c220 here in the states

[@swrdatsrackz]

Flexx Alexander loool it must be a uk/European thing then😂

[@porschemons9272]

is it real carbon fiber?

[@TheFlexxGarage]

I don't know. To my knowledge it is. It's super light and very strong.

[@porschemons9272]

alright but it looks really nice on the car

[@bobbrown6281]

You should have used pop rivets that they use for boats to secure your pieces.

[@lsosa3743]

Zip ties break easily due to heat. I agree, a rivet a a great option, and easy to remove. Drill once everything is in place to prevent multiple holes. Love your channel. I also love that your wife is getting into it.

[@wilsunmenor1373]

Hey Flexx. Thanks for the vids. Learned a lot from the past vids. Got a question on your carbon fiber large fin diffuser replacement: How did you end up installing the upper portion the bracket? I saw that you drilled holes on the upper tabs and used tie-wraps without using the bracket tabs, since it didn’t work with the new diffuser. Just curious... I’m having the same issues. Thanks, man. Wilsun

[@kevinuchiha434]

Did you end up mounting the diffuser on? Just got mine today & I need to drill holes also & the support bracket as well

[@patrickdelpopolo1531]

Hey they are currently out of stock on both links, would you maybe be able to help me find one that would work with my 2013 C300 sport 4matic?

[@rifle]

How well are the zipties holding up? Is there any play in the diffuser, or is it on there solid?

[@TheFlexxGarage]

Solid. Just washed the car today and everything was firm. I might reward them with metal tie wraps when summer comes.

[@59sttrackplayer80]

Your a C class God flex had a question...do you know if the rear diffuser on the c63 w204 will fit a stock c300???

[@dasharaathvellayan918]

Will this work on c250 avantgrande or bleuefficiency?

[@thenanook]

nice video

[@sergiosanmartin7825]

Beautiful work bro!!! greetings from Chile!!! I have a Mercedes Benz C 350 year 2012, if you can share the contact to buy the complete kit of the front and rear diffuser plus the carbon fiber spoiler, I would be very grateful... hug!!!

[@TheFlexxGarage]

Every mod video shows where you can buy the parts in the video description.

[@alerodrigvez4956]

Do you think this method would work on a pre facelift c300?

[@magicnoodle1735]

Hey would this fit on a 2011 c250 sedan that doesn’t have the amg bumper? If not do u know of any others that do fit. Thanks In advance.

[@TheFlexxGarage]

No. Won’t fit. You need to get a sport bumper for your 2011 and then change the oem diffuser on that bumper to a carbon diffuser that has big fins made specific for that bumper.

[@allex___a1031]

Would I be able to use a 2008-2011 differs on my 2013 C250 coupe?

[@garrettcollins3882]

Where could I find a diffuser like this for a 2008 c350???

[@chickens366]

This looks clean as FUCKKK

[@TheFlexxGarage]

Thanks? haha

Where do you get the black chrome accent for the trunk that runs along under the Mercedes logo? Links maybe if possible, and what about black chrome for around the windows on the side window

[@groovyruben7776]

Brembo swap

[@TheFlexxGarage]

No way. Waste of money on a c250. It’s not a car making tons of power that needs crazy stopping power. I rather spend money on other mods.

[@cloutboy11]

Will this work on a 2012 c300??

[@AidanAnderson-kl8ck]

is this the same for the non facelift model?

[@TheFlexxGarage]

No. They have different bumpers and requires different diffusers.

[@omaraguilar3956]

So u just went with no supports ?

[@TheFlexxGarage]

yup

[@petersonandprestongo5332]

where did you purchase the front splitter???

[@TheFlexxGarage]

Go watch my other videos. Link is in the description. kzbin.info/www/bejne/emmUqol4mbuiaa8

[@AznShadowWc]

getting mine done as I’m typing this. they gonna install screws instead of zip ties

[@AznShadowWc]

results look soo good! used same diffuser and tips in this video. straight piped and sounds good! my friend is so jealous haha

[@YamahPopal]

Now when you installed the screws did you just push the diffuser into what could be fitted then screw afterwards?

[@audiogram5332]

Hey do you need to jack the back up to do the defuser?

[@TheFlexxGarage]

No but it makes it easier

[@audiogram5332]

@@TheFlexxGarage lol well yea, but I meant did you? It's not clear on the vid If you had it lifted up. I have some insane speed bumps in my area I usually use them. Also I wanted to ask you .. remember when you did the flowmaster 10 ? Did you go stainless and what do you think is a good price? I live in Canada so it's not really the same for dollar value but I was quoted at $1000 today. I feel it's too much

[@TheFlexxGarage]

I don’t remember. Probably aluminum to save money. I think I spent $350-500 on labor to weld in muffler, run custom pipes to the back and weld on the tips.

[@user-ix4eo2it4d]

Will you sell me your amg diffuser?

[@mc-p303king6]

Would this fit my 2013 mercedes c300 4matic

[@TheFlexxGarage]

Only if you have the sport rear bumper like mine in the video. It won’t work on the luxury rear bumper.

[@mc-p303king6]

@@TheFlexxGarage ok thanks for replying 👍

[@wandersonbatista5396]

Yes

[@its_MSR]

​@The Flexx Garage how do you know if it's sports bumper

[@TheFlexxGarage]

As mentioned above, a sport rear bumper looks like mine. A luxury/base rear bumper doesn’t look the same. Look at the outline of the bumper area at the top of the diffuser.

[@fishingstix610]

It would look better gloss black instead of fake carbon fiber wrapped

[@mitchio83]

It's real carbon fiber, carbon fiber on this car works because AMG uses a lot of stock carbon fiber pieces so it makes sense to trim a C class in carbon fiber. More of a luxury/premium vibe than ricer stick-on shit.

[@muhaameddrammeh8514]

Is lowering the car on HR sport springs on your list?

[@TheFlexxGarage]

Muhaamed Drammeh , still TBD. The reason is because I daily drive my car in New England and there's tons of bumps and potholes and also I take my car snowboarding a lot so I do drive it in snow. The cars stock height is already pretty good and there's not a lot of gap in the wheel well. However I do love the "tucked" look of wheels but I would probably scrape the bottom of my car more often and risk ruining my splitter and diffuser. So yeah....I'm still torn on what to do. Ideally is to do an airbag suspension but way too pricey.

[@ask4george1]

It looks a little odd. I was going to get one for my CLS55 AMG, but I think I'll just get the carbon fiber, no big fin.

[@01JenMel]

Wow your car looks great. When you tie wrap the bottom diffuser to the bolt up hole was it the hole previously used for the support trim piece? Or did you make a new hole?

[@TheFlexxGarage]

Yes, the hole is already part of the car and was used for the original support plastic bars.
