Header cat back system?

[Rx450sc]

I hate my dynatech headers. There is a problem with the routing of the 2 rear spark plug wires on the driver side. Even with the longer wires they are now including in kit. They do burn on the header tubes. Their high flow cats are not the best quality. I have had to replace them already. Since day one I have had problems with leakage at the collector flanges. I am waiting for Kooks to come out with their long tube setups to replace the dynatechs.
