I have their 3" system on my 69 Shelby, the only issue I have is the pipes between the x-pipe & the headers, but I didn't want to scallop the trans crossmember. I "adjusted" the tubes with a BFH & will have to live with them being a little low.
(This is a 418w stroker with FPA's)
I would be curious as to what everyone else has done for tail pipe hangers though, the hangers they sent are really lame. I still need to figure that part out, I don't have my car on the road yet.
I was overall pleased with the kit, though.
