I don't see the resonated mid pipe on your site......

 

its there, on a drop down menu in the middle of the page; price for the resonator is $248; non-resonated pipe is $173.

 

Use the drop down option to select resonator and it will change the price and that will get the resonator version for you

 

Just a tip for exhaust shoppers - if there's a quality exhaust shop in your area, talk to them. There's a well regarded shop here in San Diego (Ed Hanson's) that does custom exhausts for about what you'd pay for an off-the-shelf aftermarket kit (they quoted me ~$650 for my Mini years ago). What's nice is they can put different mufflers on so you can get the volume to your liking. While I was there last month (getting my stock exhaust repaired) they were working on a Hellcat and had the car's owner come out and sit in the car so he could listen to it before they finished up. They said that's their standard procedure. I thought that was cool and never would've thought of it.
