It works on a 2 door but I just bought the exhaust from Summit Racing not the complete kit. Sorry I don't have better pics to post but it looks the same as the OP's pics.

 

I've been running this for 2 years now. It's great, the muffler is tucked up out if the way....but I do have a few dents in it. For those people looking to run it I would suggest you only buy the muffler and just measure and cut your current exhaust to fit. It's easy and cheaper.

 

Would you need an additional hanger for the muffler?

 

On the four door you don't need any additional hangers (don't know what the 2 door looks like). The muffler sits between two hangers. You only need two exhaust clamps to attach the muffler to the exhaust pipe.

 

Does anyone know the part number for the band clamps that comes with this kit

 

Im a huge Dynomax fan. Here is a link to an install I did using off the shelf parts. DIY muffler relocation with Dynomax Parts

 

Just purchased this kit for my other Jeep. I have the Dynomax 39510 Dual System that I purchased just over a year ago and it has already rusted at the welds and in the center of the muffler. Hope I don't regret staying with Dynomax on this one. Anyone know if there is a warranty for rust on these things? Its not like I live in the rust belt. Either way, the 39522 seems like it will be better.

 

Do you get more dust or exhaust smell with down pipe pre axle?

 

I haven't gotten any exhaust smell maybe only little bit of dust.

 

I've not gotten any dust or smell either.
