The only issue I see is the kit says it fits 67-69 Cuda's and 67-74 Darts/Demons/Dusters/Valiants and tail pipes for a Cuda are designed to exit in a totally different place than pipes for a Dart. I put a similar system on mine and ran into that issue and had to cut the tail pipes off right behind the axle and add straight sections to bring it out in the right place. Wasn't hard to do but I was a little frustrated to learn that it didn't really fit right. I'm not saying that positively the kit your looking at there will have that issue, but it's a possibility. The tail pipes were a little close in spots where they went over the axle and past the shocks and fuel tank but they clear.
A mandrel bent system is way better than a standard crimped tube exhaust like most shops do.
