I just bought some insulation materials today and stuff it under my trunk.
Ya the drone is reduced like 50%... but still some
looking forward to the magnaflow mufflers xD

hey richard let me know how your setup turns out. I had the exact problem and ended up throwing back on my stock mufflers. btw my name is richard too ^^

you should try to get pipe resonators placed after the xpipe for each side. shouldn't cost much <$200. it should dramatically reduce the drone + whatever you already reduced with the insulin material. My friend did that on his E320 and it did wonders.

The only practical place is the spare tire well, really. That's where I did mine.

Hey Richard. My setup is pretty much done for now. Magnaflow x-pipe and magnaflow mufflers with Dynomat in the spare tire well (didn't do much as far as sound dampening goes if you ask me). The first few months, the increased cabin noise REALLY bothered me, but now, it rarely irritates me. I've asked most of my passengers, and none have said it got on their nerves. Works for me. Overall, I like it.

I installed this magnaflow muffler today.. I put it right behind the xpipe
BUT!!! I can still hear the drone sound!!
This cost me $180 because they remade the entire pipes to the tips...
where can I buy these dynamat...I really want to get rid of that drone sound..

You should add 2 more magnaflow mufflers where the original mufflers were. That'd be an interesting setup. 3 mufflers.
But about the dynomat, you'd probably need to order it online, but I think some car audio shops carry dynomat or some sound deadening material.

I'd say it's probably still louder than stock. You went through so much work to get that 1 muffler after the x-pipe, but it still drones, so I came up with the 3 muffler idea. Haha.
Honestly, I think you'd be quite satisfied with the setup that many people have, x-pipe and 2 magnaflow mufflers.

I wonder how just removing the mufflers and keeping the stock resonator would sound, and not replacing it with an X pipe. No drone from keeping the resonator but louder and more aggro?

It would probably still drone. A resonator only reduces drone, doesn't eliminate it necessarily.

the only way to get rid of the drone is to have the stock or aftermarket resonators installed. Personally an Xpipe is a waste of money IMO, unless your doing mufflers and want that loud sound. I had magnaflow race mufflers w teh stock resonator and it was badass, I got meisterschafts now and have aftermarket resonators and its sounds badass still, with NO drone in the cabin. U gotta remember where the resonator is on the car, right under the rear floor, theres only sheetmetal there. You can def use dynamat or something similar to help shield the noise, the MB factory uses that shiny tin heatshield stuff, thats all really. I lined the bottom of my cars exhaust tunnel w dynamat xtreme just to be safe all the way back. You can even do something like AZN300 did he lined his whole trunk w second skin w 2 layers I think. Either way no resonator equals drone in the cabin.....

Then your going to need a car lift dude lol. Also I saw that it appeared you put house insulation in your trunk. Thats not for sound, just temperature. Dynamat is the way to go.

for real?? lol
damn ya thats what my friend said too
how come I heard a decrease when I stuff it randomly in my trunk
BUT !! no decrease when spend like 2 hours cutting it to pieces to fit inside the spare tire trunk..

You can stuff your trunk with anything and it will help a little, but dynamat is purpose built and will specifically target sound. Fiberglass insulation is a poor sound insulator...very porous. Think how a sieve lets water through but a plastic bag holds it. I'm sure you can find dynamat for cheap tho don't worry. Your most effective point to insulate is going to be under the car specifically where the resonator was.
