The sound and performance of the exhaust system will be based off many factors. The design, construction materials, and material thicknesses will all factor into the quality of the system.If you want to avoid a "ricey" sound, look for an exhaust system that uses a resonator and a smaller exhaust tip(s).As far as horsepower increases go, it will depend on the condition of your motor, the other mods done to it, and the design of the exhaust system itself. On your B18B, you should be able to see around a 10 hp gain from a header, high flow cat, and cat back exhaust system. It's normally the header that makes the biggest difference.
