I'm trying to install a good and loud exhaust system. I love the 2015 mustang flowmaster outlaws sound and would install those (if i had a mustang). I'm wondering if i could install them on a 2008 w204.

They're relatively small, so they look like they would fit. Would there be a pressure issue or something? Will it work if it fits?

 

you want your C300 to sound like a mustang?

 

agreed- that's a stretch and not a good one IMO.
I can tell you Flowmaster has a lot of different styles and shapes of mufflers , and I would think one of them would fit . I would NOT recommend an outlaw or series 10 muffler for your MB, that would sound awful!. Maybe a 60 series muffler would be good if you are looking at flommaster?. Those are designed for the 4&6 cyl applications

 

You can just go to a muffler shop and have them replace your mufflers with some universal Flowmaster ones. I personally had a resonator delete and replaced the mufflers with Magnaflow ones. Very drone-y from 2.5K-3K. Maybe it wouldn't have been drone-y if I had kept the resonator.

Now, I have deleted all resonators (1 big one, 2 small ones) and have stock mufflers back on. Sounds good and not obnoxious at all.

 

I heard a V6 mustang with outlaws and it sounded pretty good. Wouldn't it be the same?

 

Muffler delete and/or resonator delete will give you noise.

 

no not at all - the engine harmonics in a mustang are far different than that of a MB - you do what you want , but I wouldn't do it on my car

 

I currently have an x-pipe in. Would straight piping it be louder?

And what kind of systems would be loud that would fit a 2008 w204? The cheapest one I found was a becker axle back for $700.

 

I just bought E63 AMG tips and had them welded in place of the mufflers. None of the prefabbed exhausts were worth it to me. Deleting the mufflers will make it significantly louder though.
