dual exhaust is fine, with proper design it won't lose low end. Its when you get into a dummy dual (single inlet/dual outlet, and unequal length) that you get into poor results.

It could be argued that clearance issues aside, a properly designed single exhaust would be best. Problem is they rarely ever are. the key is a proper merge. You also have the advantage of costing less in materials, and weighing less.

Havent peeked under but it appears that the WK2 models all have true dual exhausts of some sort so dual exhaust makes the most sense.

Tuning won't be here anytime soon. The software in its current phase can't write to the PCM.

This confirms it now I have to convince someone who installed a corsa or borla to ship me their unsused hemi exhaust.

Re: 3.6 dual exhaust

For 3.6, if you use other mufflers for V8, you will loose pressure. So, go with smaller diameter tubing for custom.

Negative....Backpressure is a myth

Looks like these exhausts are 2.5" duals, that would be fine for a 300+ hp V6.

So are you saying here that just from the exhaust going duals you should be getting 300+hp?

And thanks for all the info guys it helps out a lot more then the dealership. I really just like the looks of the dual exhausts so if it doesn't cause do anything performance wise I don't mind as long as it doesn't cause any problems tho.

Well, the Pentastar makes 290 in the Jeep...Yeah, it's possible. From the few people modifying these so far, they are reacting well to mods...No tuning necessary. The ported TB in my sig certainly helped the Chrysler 200 I did my testing on, even with no other modifications.

I'm personally excited with this engine, I think it has alot of potential. I recently saw a intake manifold for one and there is definitely room for improvement.

Re: 3.6 dual exhaust

That's pretty good news. I don't want to do too many mods to my jeep mostly visual mods probably just an intake and exhaust for performance so it doesn't feel so sluggish. The Jeep is mostly my winter car and my girlfriends full time car. I have a summer car which I want to be more performance based.

I already checked with custom muffler shop before. Considering Pentastar's picky low end tourque(according to the dyno), they recommended smaller diameter custom product.

Sorry, not trying to be rude here, but that's simply incorrect. Chrysler's dyno indicates the engine makes at least 240 flywheel tq from 1800 to 5800 rpm. Thats pretty impressive for such a small motor, and a wide range of rpm.

EDIT: What people dont realize when they are looking at Airaid's, or K&N, or say Magnaflow's dyno results is that because of the transmission mapping and the inability to control it to hold in a gear, they have to start at say, 3000 rpm just to have a complete dyno run without the transmission forcing a downshift, ruining the run and making the results invalid.

Well, it could. But for better numbers, if I mod exhaust, I will go with custom one with smaller diameter instead of the one for Hemi.

Re: 3.6 dual exhaust

I don't know if this is right but what i'm thinking is 2.5" piping is the way to go. My only reasoning on this is cause I also own a 2.0T Genesis and the exhaust for the 2.0T and 3.8 are both 2.5" duals for all the after market exhausts and it seems like they are getting pretty good dyno results. I don't know much about all this stuff but it just seems to me that 2.5" is the way to go off of that observation.
