You will ALWAYS get greater hp yields on your car with your early stage mods than if you install the same mods during the late stage modding process. If you have 4 mods, each claiming/delivering 10 hp you do not get a combined number of 40 hp.

Agree.... so it seems, assuming other dynos verify similar results, that the smart money will add the plenum first to the stock CS, spending what... maybe $50/hp gain...and then have to really think twice about spending $2-3K for a complete exhaust system that will then offer much lower hp gain....spending ~$200-300/hp gain? Pending further testing, my money's on the plenum...forget the exhaust...stock sounds fine to me.
