I found a thread here about a month ago with the QuietCrawler Exhaust after being quite disappointed with the Magaflow Off Road Pro that I bought for my 2012 4 door. Since the kit is out of stock I messaged Dynomax and they gave me a sheet with possible parts to order to piece together my own kit, and that's what I did. I ordered everything form Summit and had the stuff next day.
1x 52561 (Pipe)
1x 17283 (Muffler)
1x 24246 (Bullet)
4x 36434 (Clamp)
2x 35337 (HD Clamp)
1x Magflow Turn Down (Unknown Part Number)
You will also need 2x 5" piece of 2.5" OD exhaust pipe. I bought an 18" piece from Autozone and chopped it down.
