The Mugen Header is reallyx quiet? isn't that true with the exhaust as well? from my understanding...the quieter ur exhaust manifold and exhaust system altogether, the less friction the exhaust gases make as passing through it...so isn't this what we want?

QUESTION: I have an AEM CAI installed right now. It's damn loud. If I put in a Mugen Sports Exhaust, and a Mugen Header, will it quiet down the AEM CAI?
