I have an 04' EX V6 Coupe and so far have only put on an AEM V2 Intake, NGK Iridiums, and a Test Pipe. I was hyped about getting new headers until I found out that the V6 headers are casted into the engine, stupid right. I'll most likely get a magna flow exhaust when I get a hold of $800 to blow but was looking for some other mods in the meantime.
