header

A header will do the following. There are two main types of headers, 4-1, and 4-2-1. A 4-1 header will give you a good HP gain on the top end, and perhaps a tad bit of torque. A 4-2-1 header is designed to give you some HP on the top end, but it will work better for low and mid range torque. Deside which one will meet your needs. As for a header changing the sound of your engine it will, especially with a good cat back exhaust.
