Bigger isn't always better in terms of exhaust. Generally yes the more free flowing the exhaust is, the higher max horsepower the engine can produce. The only thing is when you free up the exhaust sometimes you run the risk of losing low end torque as a result of decreased back pressure. Especially in our engines that aren't exactly powerhouse's you want to get the right mix of maintaining some back pressure for low end torque and having a freer flow for high rpm horsepower. Unless your on the highway all the time you may want that very desirable torque for acceleration purposes.
