C300 X-Pipe: Using Resonated vs. Unresonated Maganflow

Hey guys,

I've done an extensive amount of research on this topic. I've watched maybe 30 videos of C300/C350s with x-pipes, and I'm a fan. I threw one in on my old G35 and it sounded GREAT, but the added noise was a but out of place on that type of sedan, IMO.

Here's what I haven't seen:
-Everyone seems to use the unresonated x-pipe; why not the resonated x-pipe?
-I love the fact that my car is DEAD silent when cruising. I assume the unresonated version has drone somewhere in the rev band, or am I mistaken?
-My thought was that the resonated x would eliminate any possibility of drone while still allowing more noise under throttle.

Here's the typical x-pipe:




Here's the resonated version:






Has anyone used this? If so, any sound clips?

I'd like to add a little more volume, but the Remus mufflers are about $1,000, and that's too much for something that's ultimately not going to make the car any quicker. I also don't want to cheapen the feel of the C300 by making it sound like a 350Z. It's sporty looking, but the lack of speed is a silly combo with a loud exhaust.

I have the un-resonated x-pipe in my car. There is no drone whatsoever. In fact you can't really tell the difference until about 4k RPM. With the windows up and driving like a normal person the car is dead quiet.

That was until I did a muffler delete. Now it's loud all the time.

I have X pipe too and I have the same result as Ders, I like it, is a great, simple and cheap mod for the result. Next step will be a Exhaust Valvetronic, to decide when I want it noisy or quiet!

Ok, this is good to know, guys. It makes me feel better about doing the unresonated version. Again, I just don't want it to be obnoxious under throttle.

Now the real question: In terms of sound, is positioning the X closer or farther from the cats preferable? I want to minimize the rasp.

No drone with my Magnaflow Tru-X pipe. Had it placed closer to the cats.

You added sound dampening material though, correct?

Would a resonator delete with straight pipes be louder/more drone than an x pipe?

Thank you in advance for any feedback.

X pipe has no drone man. I replaced my resonator with an x pipe and the only time it's slightly loud is around 4-5K RPM. Other times it's about dead silent.

Right, I added sound dampening, but that was for when I added the Meisterschaft exhaust. I don't think a straight pipe would necessarily make it louder than an X pipe... maybe slightly more raspier.

Any chance you can post a video of your setup or an in cabin video? I recently got the x pipe and still to quite for my taste. Have to rev really high to hear the exhaust. Looking into getting muffler deletes but afraid of rasp or drone.

It's post cat so no codes will be thrown and most dealers won't care. It's more for sound aesthetics.

You know, I tell my wife that same thing when picking up a new car.... "Honey, I'm done modding. This is going to be my daily. Maybe just a couple cosmetic stuff here and there, but nothing extreme!"

..........a couple months later, she's sporting a custom widebody, slammed on coils or bagged on forged wheels lol.....


Modifiers all have vehicular OCD..... an unfinished build or incomplete vision can't be left alone...

Lawson x pipe 2009 c350

Put x pipe on a couple weeks ago. Never thought it would sound as good as it does. MPG slightly improved. 28.8 mpg the other night. Mix of highway and city driving.
