All of that really depends on the tune and which headers you get. In N/A applications, you aren't really going to see any major increase from anything after header (i.e. overpipe/frontpipe/midpipe/axleback). Anyone can correct me on this, but with headers & tune it should be around 10-20whp. Tune is what makes the biggest difference. A local tuner will be able to get you the most out of a tune compared to OTS tunes.
