Magnaflow w/ 390 GT Exh. Manifolds

[SunnDogg 18]

Looking at picking up the Magnaflow 15816 2.5" exhaust kit for my 69 S-code 4 spd. project using the stock exhaust manifolds. I'm interested in knowing if the kit actually does provide everything you need to bolt it up or if the connection at the manifold needs to be done at an exhaust shop.

 

Thanks in advance.
