I'm sure others know more, but Patricks carries a complete system or so I've heard. After installing fentons on my 62 Chevy, I took it to a local exhaust shop with a dual muffler I had already bought from Patricks. It took them less than 4 hours to complete the truck and charged me $300. I also checked with a performance shop who did custom mandrel bent stainless systems. They ballparked the cost at $900 - $1000. Let us know if you find anything else. Good luck!
