Anybody use Summit's exhaust kit

Just got the new Summit catalog and was thumbing through it and noticed they've got a heck of a good price on a mandrel bent alluminized exhaust kit for 67-69 Cuda's. The 2-1/2" kit is only $200 with mufflers. Just wondering if anybody here has used one of these kits and if so what they think about it. How did it fit?... Etc...
