Ha! Thanks for the advice. Are installing the headers the PITA or the emissions hoops you have to jump through afterwards and persistent CEL on the PITA? From everything Iíve read it always seemed to me that headers were the most efficient way to boost power on the m54, no? With the stock manifolds in place I canít imagine much benefit coming from anything you bolt on behind them, unless youíre just after the sound (which I am also).
