Ahah glad to help, I personally either like it quiet or loud ... its in the middle right now 
if it was a little quieter I would like it, but my firends all say it sounds better no, more solid and dont get bubbly backfire sounds

This is the next mod. No glass packs at fort to see how I like it. I had a 60' VW bug with headers and a 12" chrome stinger as a daily driver with no interior insulation at all so this should be plenty quiet. Ha ha. Got a video yet mixed?

So I have a problem I have the X pipe with no mufflers on my C350, it does get a little drone sometimes but I love the sound.... after I changed my exhaust tips to get the quad set up it made my car even louder, I did not go with the original oval tip set up. I am about to put headers on next week and I'm going to remove two of the cats I am worried that it will make it too loud because it's already borderline as is, I was thinking about putting on a glass pack but I wasn't sure what kind because I don't really want to change the exhaust note I just want to control it and bring it back down to where it was. I would like to try and stay away from mufflers because they do alter the sound from research I've done. If I had to change the exhaust note I would just want to go deeper and stay away from rasp. No pun intended with "goin deeper" lol any recommendations?

Hahah I order the magnaflow muffler! about $100 bucks and they rebuild all the pipes after xpipe to install it so it cost another $180 = $280 I spent to put it on
It's a big difference outside much quieter...inside is better too... but still drone at 2500rpm
ordered dynamat going to put it under my car as soon as I get it..

Finished installing my headers today, it's straight pipe with an x after the secondary cats so I will def need some glass packs, they are WAY to loud....I loved the x pipe set up w/o mufflers but with these headers i feel like I'm in a 280hp NASCAR -.- lol any reccomemdation? I want to bring the sound down and maybe a little deeper if anything...

glass packs get 4 2 where mufflers go and two where the secondary cats in front of x pipe. or get a muffler installed infront of xpipe and glasspacks at oem muffler spot

Well problem solved... I went to my friends muffler shop and he just happened
2 18 inch resonators glass packs left that did wonders. He put them between the primary and secondary cats which is obviously before the X pipe. It is a lot quieter and very smooth, it's very low when you're cruising, and like the beast when you punch it. Maybe a little too much for some think it's just fine.

Nice to hear your problems is solved...
So...Help me LOL
what kind of glasspack do you use?? the magnaflow one?
I think I will do the setup Mixedfruit suggest: magnaflow muffler after xpipe and glasspacks installed at where the OEM mufflers is....
hope this gonna work out)
The 2300-2500 drone is driving me crazy....

No need for an x pipe with mufflers. It makes no sound with the mufflers, I just keep it since I have no mufflers, it help me from loosing too much back pressure. I didnt see the brand since they were some he had extra and honestly I dont think they were a name brand. Most brands stamp thier product and this one wasnt. And how will u put glass packs where the OEM mufflers are if you're already gona put magna flow mufflers? If you put mufflers where the originals are I think you should put the glass packs by the primary and secondary cat. And try one at a time...do mufflers first, let them break in and if it's still too much do glass pack. A lot of people do things and if they don't like it they automatically say no, it's important to let your exhaust break in because it does quite down. Well with what ever you do good luck!

hahaa glasspacks will fit because I already put the muffler (dual/dual) at the place where resonator is and it's also right after xpipe~~I still think it is too loud at 2500 so I decided to put more stuff LOL

i know this forum is old but i just had my x-pipe installed and am now looking into installing borla ProXS mufflers. My question is will the mufflers fit and if so which do i need to get...also what can i expect to gain from them?

interesting, I put a cherrybomb on my first car, 91 civic hatchback back in highschool because it was cheap and the stock one was rotted through. Didn't think the benz crowd would be into such a cheap thing haha. But hey, whatever gets the desired results

Haha, no sweat, the forum is all for learning. I got two 12" long 2.25" inlet cherrybomb glasspacks. However, some may not like cherry bombs as they are RED. Lol.
If I were to do it again, I would measure the distance of the stock resonator (which is pretty darn long) and/or measure from the cats to the end of the resonator (where the pipes start to bend) and get the optimal pipe size after the length of the x-pipe is taken into account.
For example: Say there is a 36" run from the cats to where the pipe starts to bend to the exhaust tips, and the x-pipe is lets say 10" long. You have a 26" area to work with, so you can get anywhere from 8"-24" depending on preference of sound. (very short ones will be a raspy sound and VERY loud), while longer ones are more traditional and have a deeper tone.
If I could fit in dual 24" long, 2.25" inlet/outlet glasspacks, and the x-pipe between the area from the cats to where the pipes bend to the exhaust tips. I would do that and so then the new pipe install is simple, and can just be straight-piped to the exhaust tips. Saving material, welds, and simplicity, keeping time and costs lower.
Also, I would recommend trying to use clamps wherever possible instead of welding (as this will help resonance). And also, when pipes need to be bent (like the striaght pipes from the glasspacks to the exhaust tips in my proposed setup), see if they can use mandrel bends. Madnrel bends ensure that the pipe doesn't lose shape in the bend, where traditional bends distort pipe shape in the bend and you lose airflow velocity (making it more restrictive). It isn't a HUGE deal, but heck, if the point of this mod is to have free-flowing less restrictive exhaust, why restrict it if you don't have to?
