mufflex muffler swap out... yes or no

I just put a 14" Mufflex Magnaflow on my 2012 Express last weekend, and to tell you the truth, it was the easiest mod that I have done, except for the tailgate EZ Down. It took me about an hour and a half, and the fitment was excellent. The only tools you need is a can of your favorite penetrating oil, 15mm deep well 3/8 drive socket, and a 3/8 ratchet (best if its a long handle ratchet).

right on great! the 14 is the loudest one am i correct?

I have Aero Turbine 3030 on both my Rams. I will post the link so you can here them before you decide.

how much did it cost ya? i was looking at the medium sound level from mufflex i dont want alot of drone in the cab. if i go with this it will cost me 260 plus shipping to canada

Aero Turbine 3030 go for $ 120 or so. The 3030XL have resonator but I would just get the 3030 and get rid of the factory resonators for the best tone. If you have dual exhaust out the back the cab noise is not that bad.

ya i have the dual exhaust. so is this just a muffler conversion ?

I had the factory muffler removed which has a T on the muffler itself. You only need 1 Aero Turbine and a T spliting off of that to the rear exhaust. You can cut both resonators off near the tips and have the shop weld in straight pipe. On "You Tube" search for Aero Turbine for more info and Amazon.com might be the cheapest place to find one online.

sounds good i will consider it, and have a look. im still leaning towards the mufflex just because of the ease of installation and the no welding

I went with the mufflex 14 MOD and it sounds great. Nice deep rumble, very little drone. Getting airaid CAI next week, should make it sound even better :smiley_thumbs_up:

air raid cai is garbage...I have 14" mufflex with k&n cai....sounds amazing!

I did a long review in the Review section but I'll paraphrase:

IF you don't have any issue getting the slip joints apart on the stock system -
IF you get the right hanger and it mounts up properly
IF you don't mind having clamped joints and are lucky enough for them not to leak -or dont care if they do..
and IF you dont mind spending more than necessary for an inferior final installation.

Then go ahead with the Mufflex system. The beauty is that you can do it yourself in the garage..... IF there are no issues.

If I could do it over again, I would just buy the same Magnaflow muffler that comes with the mufflex for less money, had it welded in and hung properly for apx. $50 and walked away with about $100 saved overall.

Do yall recommend removing the resonators when adding the Mufflex 14?

Bikenut it sounds like you had some real issues with yours, sorry to hear that. Mine was easy to put on and I never had a problem with it, it's been about 2 years.

I'll be following this!
I already installed a K&N CAI and debating on a 14" or 18" mufflex.
I can't stand drone but do want a lower tone.

Keep us posted.

any sound clips of your setup?
How is the sound in the cabin? How is the sound when the MDS kicks in?

18" Mufflex single is loud, but not as extreme as the 14". The 18" has a great sound on the highway even with MDS engaged. But for me, around town it was just little too loud.
