Headers have always been one of the go to performance upgrades that everyone wants on their high performance car or truck. And back in the day they were one of the first performance mods people would do. But for late model cars a set of headers can be expensive, can effect emissions compliance, and can be a challenge to install. So if you have an LS powered late model ride with a supercharger you want to know just how much power you can expect from a header upgrade. We know we would love to have that info before making a purchase, and thanks to Richard Holdener that info is right here.

Yes, your combo may be slightly different than this one, but it gives you some information and trending data that you can use to make your own purchasing decision.

As usual, Richard tests the combo with both stock manifolds and headers, and then discusses the results. If you are new to Richard’s videos, then pay attention because there is more to learn here than just the actual test in this video. If you listen, he’s constantly sharing other info that you will find useful and that he’s talking about very matter of fact because it is the kind of thing he knows well from his testing. For example, the topic of exhaust collectors is something he talks about briefly in this video. Pay attention.
