I just picked up a 93 SunSport. The PO said he had a crossover muffler removed which was supposedly located just after the manifolds inside the engine compartment. Has anyone ever heard/seen this? This was replaced with standard rubber exhaust hoses, which are all I've ever seen on a direct drive. Anyway, I'd like to quiet it down a bit. Can I install mufflers under the tank? Any recommends for type or brand.

1993 SunSport, PCM 351, carb.

Thanks
