Exhaust options

Just have a few questions about the new GC's. Ive noticed that full catback systems are a little on the expensive side (at least in my book anyway). I was wondering if you can just put new mufflers on the GC's or is the way the exhaust is ran prevent that option. I've always had trucks before and just cut the factory mufflers off and put a flowmaster in their place. I don't want anything ridiculous lout b/c I bought it for the wife but I would like to be able to hear it when i use the remote start. As a side note, I really don't see how Jeep was able to quiet these hemis down so much anyway. They are much quieter than the stock rams

Thanks for any suggestions.

you can always go with custom exhaust, or just spring for a catback system.
i like a system because there's minimal cuts and welding points, and tips that look like they belong on the vehicle...

Check performancepeddler(dot)com for your exhaust. The Magnaflow MSRP's at like $1200 but this website sells them for like $850. I have bought my last 3 exhausts from them, excellent communication and excellent service.

I am not 100% sure but if you have, or plan on adding, skid plates I do not think that aftermarket exhausts will fit.

Don't go with the Magnaflow Cat Back. I did and I hate it. Not loud at all and a horrible drone and highway speeds. Borla's should be out this month, wait for that.

The Borla is going to be the best option for me but I'm still not sure!

Do you guys know if Mopar will come out with an exhaust soon?

chances are- your going to get a drone with any aftermarket setup due to the MDS (when your hemi goes to 4 cylinders). Unless you get a tune (like Diablo when it comes out) that cancels MDS.

Or you can change to a heavier weight oil which will provided better protection for the motor, and cancel out the MDS on its own

Has anyone purchased the Borla Exhaust for the 5.7 yet? If so what are your reviews on it and how does it sound from inside? Is it to loud or is it manageable??

or run around in tow/haul mode, or move the shifter to the left and drive in "5" all the time.

I haven't even crawled under to look at the exhaust yet, is it 2 separate mufflers or 1 big one like some cars?

I would like to hear our exhaust with the mufflers removed but the resonators still in place. I wonder if it would be loud enough and still not have the drone???

Two resonators > one two camber cat. < two mufflers at the tail.

One muffler can be unbolted at the muffler, the other one is welded to the pipe going to the cat.
