2014 grand cherokee magnaflow exhaust
So I was thinking of doing this, getting a dual in dual out magnaflow muffler and eliminating the big stock bulkey ones and eliminating the resinators and adding a 4" pipe? Anybody have any suggestions or any help on how I should go about doing this or if u have the same thing please leave some feedback

Did the same thing on my 2011 5.7 (assuming you have the Hemi), and also deleted the stock resonators and added 4" stainless steel tips. Here is a short start up video after the install.

Forgot to mention this is the 11386 dual in dual out 14" magnaflow muffler with the built in tru x pipe. Hope this helps.

Did u use the stock piping or did u customize the aftermarket magnaflow exhaust they offer?

Also, does ur car with that exhaust setup give u any problems like with the eco mode kicking in or it going in 4 cylinder mode?

You will have to use new piping to make the muffler work, and obviously new piping once you delete your resonators. I have no issues with the new exhaust, I may have lost a little low end torque but some say that's to be expected. The MDS still works as it should. If I need to I can turn it off via the diablo.

I tried to get a 11386 magnaflow installed last week and it looked like it would be a lot of work so I held off... How did you get yours installed around the driveshaft? It looked like it would end up hanging down a bunch?

Would you mind posting a pic of it installed?
