any experience with this bolt on exhaust?

[70chevrolet]

summit racing is selling a complete hooker exhaust system (less mufflers) for my 65 c-10 short-bed for $199. Two local shops quoted me between $500-$600 for a complete exhaust with cherry bomb mufflers (which cost like $15 each). Summit has the systems for both headers and exhaust manifolds.
I would hate to burn $200 on this thing and then have to take it to a shop and pay them another $300 to get it to work, putting me in the realm of a the custom system that I really want.. I have a friend that once had wicked good luck with complete exhaust systems from summit but it was for a camaro and it was not a hooker system (he said that the pipe was pretty cheap but the fitment was awesome). It would be nice if someone has used this particular kit and knows if it is junk or if it will bolt right up. I do have basic fab skills and a mig welder in my garage. My setup is just a SBC with rams horn manifolds which I believe were factory that year on the 327.

If anyone has used this kit has an opinion, I would love to hear it...

Thanks!
