Is there a after market exhaust system or muffler that will help a 2007 Hemi get more torque? I am looking at 3 inch SI/SO. I DO NOT want any thing loud, just something to help improve towing.

Typically it'll be back pressure that will give you torque, but that's also up for debate so I would say no. To increase torque you might want to look into a programmer. SCT makes a great one. I'm sure there are some engine mods you can do too. On the 360's a set of 1.7 roller rockers will do the trick but I'm not 100% sure about the Hemi's. Go to DodgeTalk I've been a member there for years. It's just like here, it's free to join. Those are the experts. Look in the 3rd gen section.
I had an issue with towing where the truck would not use the proper gear for the situation. Mine has 3:55 gears towing the trailer in my signature below. The truck tows fine on the flats but when climbing hills it downshifts goes up a few mph then upshifts and continues back and forth (hunting). I'm not sure if that's your problem. A programmer will add a little more torque and hp to a gas engine but not enough to justify the cost. Where the cost was justified, in my case, is in shifting performance. The truck now stays in the right gear for the job and the hunting was eliminated. The downside (and upside) of a programmer is they require higher octane gas usage with a slight increase in mileage. I use a Superchips programmer with towing mode and would never go back. The extra cost is worth it in my case but it may not be for others.
I also added a Borla dual exhaust but the real gains were felt when using the programmer.
I assume your looking for better towing. If that's the case gears will help a lot too. But if you have a 4x4 you have to do the front as well as the back. That can get pricey, that's why I haven't done mine yet.
