That sucks about your radiator. I just recently had mine replaced as well. Oddly enough I had to get a new overflow tank too. That Damn float sensor in there sucks. Another weak part we should thank Mazda for. Anyways as of right now I do still have the exhaust. I keep going between wanting to sell it or keeping it. It's sitting on a shelf in my garage till I get a new catalytic converter. It's a bit too loud with my midpipe on. Let me know if you decide to shop for exhausts again. I might very well still have it and be willing to part with it, since I want mods for my new bike.
