We have a system that relocates the muffler under the JK and empties out the back.
P/N 39524, this is for the 3.6.
Dynomax® Performance Exhaust | 2012 JEEP Wrangler 2 Door 3.6L V6: Single - 2.5" Cat-Back system, 4" Polished Stainless Steel Tip, Ultra Flo Polished Muffler
In regards to drone, there can be or might not be depending on how fast you go, and if your cruise speed is in the "drone zone".

+1 on the AFE high tuck - I have the 2.5 on an Unlimited. Like the sound and in conjunction with a K&N filter got some mild power plus mpg gains. Definitely not a power drop. I'd do it again any time

I would not touch the factory exhaust unless you really want a different sound.
There are many guys on the forum who have degraded their performance by messing with the exhaust on the new motor.
Truth be told...most vehicles these days have just about all the power squeezed out of them from the factory with regards to breathing and exhaust. Vehicles that benefit from intakes and exhaust the most are forced induction.
Now I know there will be a whole host of people on here that will disagree, but I think the 3.6 is great the way it sits. I would not mess with the exhaust to try and gain power. Sound is another matter.

its an upgrade im considering and im curious why you guys are keeping the rear muffler ?
IMO If im gonna do this, i might as well gain some ground clearance too & get rid of the low hanging rear muffler all together.
Im seeing pricing on the AFE system below (2.5inch @ $366 & 3 inch @ $418)
I dont believe this engine would benefit from the larger 3 inch...i think it needs the back pressure.
oh crap ! afe doesnt make either of these systems for a 2 door (WTH) !?!?!

There are plenty of other options but most all regardless of who makes them will need a bit of love to make them fit perfect no matter what.

Does anyone know of an exhaust like the AFE or dynomax that relocates, but doesn't add some god awful loud noise? I think it's silly as hell to purposely make a quiet vehicle noisy just for the sake of sounding falsely powerful...
