C300 exhaust upgrades
Anyone play around with their exhausts on the c300s yet? Im considering a muffler and resonator delete but im not sure how it sounds. Also cant find any exhaust systems to buy for the w205s.

The link you posted is for 400 not a 300 which is what he is looking for, im sure there is a major difference between the 2. I am also waiting to see people with 300 exhaust systems done, as im curious for when mine shows up.

Been considering doing the same to mine, but hoping to hear vid or other people's opinions who have tried it.

My video (in the link above) is on a C300. Unlike the C400, though, I just did the muffler delete. One month later and I am still very happy with my decision.

I'm not sure where you're located, but at the shop I went to in LA they cut my mufflers, turned on my car, gave it a few revs, and asked me if I liked it enough to keep it that way or to reinstall the mufflers. It might be worth a shot.

Sorry for the late reply, but i just saw ur youtube video. I loved the agressive sound it made! The stock exhaust sounds too quiet in my opinion. How much did ur shop charge u to delete ur muffler? And does it void ur warranty? And did u play around with the resonators yet?

Thanks, and I agree about the stock system being too quiet. As time has gone by, the note has become a noticeably deeper, in a good way.
If I remember correctly, it was about $110. Definitely not more than $120. I was in and out in about 35 minutes. It was a small shop and had a Yelp coupon that I was able to use.
The short answer to your warranty question is no. This comes from speaking to the parts department at my dealership, as well as reading online. However, I'm taking their word with a grain of salt, because I'm sure if something were to go wrong with my engine (knock on wood), they'd find some way to tie it to this "modification". Luckily, I kept the stock mufflers. So, if something starts acting wacky, I'm gonna take it back to the shop and reinstall them before heading to the dealership.
I decided to not play around with the resonators for multiple reasons. For one, all the videos I watched on Youtube and all the threads on here make it seem like droning is a big issue. Those videos also had a lot of exhaust notes that were more annoying that aggressive, so naturally I wanted to avoid that. Lastly, I didn't want to jeopardize a loss in back pressure, even though I knew turbo engines are supposedly able to create enough pressure for the loss from deletes to be negligible.

X pipe, resonator delete
I have a 2011 c300, I removed the 2 small resonators, and replaced the large one with the X-pipe, it sounds Amazing!! Hardly any drone when cruising around at the same speed, can't hear over a little music, but sounds so good under acceleration!! YouTube videos and videos I've taken just don't match up to how it sounds in person. Highly recommended
