Does the Magnaflow 10790, The 2.25" fit the facelift cars the 2012 and 2013 C350s? Coupe and Sedans are the same?

I have a 2013 C350 Coupe 4matic, and want to add x pipe, no idea if this will fit or not.

I believe it will fit yours. I'm not completely sure so I'd wait for someone else who actually has a 2013 to chime in as well.

how long did it take? also how much did they charge?

Do you guys know how much it cost to install an x pipe on a c 350 coupe. Many shops are telling me $700 because they have to weld it. Or should I just get an Eurocharge Ecu, brentuning, or oe tune? oe tune is the cheapest and it boosts 24-30 hp and 20-30 lb fits torque. Please let me know what you guys think.

I paid $70, anyone trying to charge you $700 is taking you for a sucker.

They said 700 because they need to weld it in and add extended pipes. I want to pay no more than $120 for labor. Can they just bolt it in.

FFM

Lol, they are ripping you off. Do not pay $700 for anything less than a full exhaust, a welded one haha.

Find another shop.

They gave me a new rate. $100 for the magna flow x pipe and $105 per hour for labor. They said it could take them three hours, but it should only take them tops 2 hours, right?

I've swapped out 2.25 magnaflow pipe from a stock resonator. Paid 2 hours labor and for pipes.. tbh... I hear rumble at lower rpm's and not much louder at higher rpm's.. My butt dyno says smoother power delivery, but that's probably placebo.

Hey guys, I know I’m a bit late but about 6 months ago I bought a 2008 C350 Sport and I absolutely love it. Last night my C let me know something was up with my left brake lights so I asked my lady friend if she could hit the brakes for me as I stood behind my car and well she accidentally hit the accelerator instead and fairly hard too 🤦🏽*♂️ However I was very impressed from what came from my exhaust, but I felt there was more potential to get a nice roar from my 350 and felt it was somewhat restricted for being a “luxury sport sedan”. It got me thinking on putting an X pipe in place of the first resonator as I did on my old mustang, but I couldn’t get all the information I needed from basic research so I’m hoping you all can help. Here are a couple of my questions.
1. I see a lot of talk about going with the magnaflow Xpipe but for such a simple mod I don’t see why a custom fab x pipe from a reputable shop wouldn’t be just as good if anything cheaper and less troublesome to install. Do you all agree with this?
(I have no concern of voided warranty as I am the second owner and if any it would no longer be valid due to age/mileage)
2. Will my car throw any engine codes due to any O2 sensors from removing the resonator? (Only asking because my mustang did.)
3. Does removing only the first set resonator do a good enough job of unrestricting airflow for a nice growl or do you suggest more work like deleting the mufflers as well. Or does anybody have a specific exhaust set up that they love for their c350?
4. If we’re only removing one set of resonators, which is the best to replace with the xpipe for the best sound? The front or rear resonators?
Side note: I’m very particular because I’m a college student and prefer not to be in and out of the shop spending extra cash trying to figure out the right set up (I don’t think anyone does for that matter) also do plan on going with a diffuser and quad tip set up down the road but that’s not for awhile.
Thank you for any help and sorry for the long post!!! Oh and I’m new here so pleasure to meet and see all of y’alls enthusiasm and love for Mercedes 😍
