it does make it worse if the exhaust is TOO clean. i beleive if you leave the reso in you can change the muffler. without the reso is the worst for the MDS.
Yes the resonator is the right be for the tailpipe (you can see it when he is waiting for the guy to rev the engine). It almost looks like another muffler! You can just replace the huge stock muffler with your magnaflow. You will only need one muffler!
My problem, fwiiw, I chopped from the muffler back and installed a flowmaster 44 that i had laying around and 3" pipe all the way back. Sounds throaty, but I'm getting the horrible drone. So I'm trying to see if there is a aftermarket resinator to purchase, other wise I'll have to buy a stock one!
In the video you can clearly see the Magnaflow logo on the "middle" muffler. Is this one the one to be changed?
Edit: it looks like there are two mufflers, one in the middle and one on the "tail". I suspect the last one being the resonator, and the middle one the magnaflow. Correct?
That would explain why I need one muffler only.. correct?
FYI - I have a 22" Borla for a 5.9 Durango I installed and removed the reso...no drone and a great sound @ WOT! It is quiet under normal driving conditions...I can still hear/feel the MDS, but no highway drone or annoyance issues.
- Can i change the muffler by my self, ie crawling underneath the car? Special keys required?
- Will the engine need a special tuning for this change?
- Any well known drawbacks, apart from disliking the sound (you never know, you can't simply judge from one video, however this muffler is so cheap I can bare the risk of throwing it a away!). Maybe decreased MPG?
Unless the new muffler is exactly the same size and configuration as the stock muffler, you will need to be able to bend exhaust pipe and do some welding to put the new muffler in.
Tuning is not necessary.
No known drawbacks.
If you dont like the factory drone, definitely don't put a muffler on. The drone of an aftermarket muffler will be minimized if you leave the factory resonators in place.
I have a dual outlet Borla ProXS muffler on my '09 Hemi Ram without resonators, and while it doesn't bother me, there is drone.
You wouldn't necessarily have to weld, if you can bend the pipe and flare the ends, you could use clamps to hold the pieces together. The main thing is that unless you can find a muffler that matchs the dimensions of the stock one exactly, it won't be a direct bolt-in.
Oh, misread the original post. You were talking about the activation/deactivation, not saying there was drone.
No I don't feel/hear any. You will notice the kick in and out more with an aftermarket muffler though.
I put a 3 in. system with a Magnaflow 14589 and two 12 inch glasspacks, one before the Magnaflow and one in the stock resonator position. When first installed it was perfect, but as the glasspacks deteriorate it is getting louder. I don't call it a drone when in the 4 cylinder mode, but it definitely has a tone change and sounds somewhat like a big ricer. It doesnt' bother me.....yet, but I can see down the line I'll need to try something else. As far as the Magnaflow goes though, while in 8 cylinder mode, it sounds great.
