future objectives

I will post more info in the future such and fuel consumption log and pics. The next mods I have in mind are thunder street headers to reduce pumping loses and rear wheel well covers. I am confident that the wheel well covers will work, but I am not so sure about the headers. The probem is; will the lower exhaust gas velosity resulting from larger diameter tubs be more than made up for by the more consistant tube diameter throughout the rest of the exhaust system? changes in tube diameter/cross section consums energy... What goes on in the exhaust system can be quit complicated.
