I'm not concerned about the exhaust note....more interested in performance.

A well designed after-market muffler will most certainly give you better sound, and, perhaps, a bit more hp. However, combined with a set of well engineered headers that incorporate longer, equal length primaries that flow into a true merge collector, together with higher quality, low cell catalytic converters will certainly result in an increase in power. Keep in mind, this application involves a delicate balance, wherein only products with excellent workmanship and designed can be utilized in order to avoid CEL's and maintain proper back pressure.
