Run it the way it is for now, then look on ebay or local auto wreckers for stock exhaust and intake parts. One of the problem with after market headers is that they use non oem conections between header and the rest of the exhaust system, so look at what is there and consider getting the whole system so that you can avoid problems. I had to re-machine the aftermarket header flang on my header so that I could use the oem parts and set up. As others have said if you want FE then the stock set up is the best starting point, and any real improvement on the stock setup would take more time and money than the average person has. I alway remember seeing a picture of a Honda engine development center that had over 100 dynomometers... and that was only one of many Honda engine development centers!
