New header = computer readjustment? - 3/15/2007 10:26:41 AM    drsmith87   Posts: 6 Joined: 10/3/2006 Status: offline  I'm new to the world of tuning (I worked more on muscle cars) and I'm looking at putting a header on my '98 Accord. The engine is completely stock, and the car is a 2-door '98 Accord EX, automatic 4 speed, completely stock.  I'm just looking to gain a little power without having to sacrifice too much fuel effeciency.  If I got a new header and maybe exhaust later, would I have to do any reprogramming to any of the sensors?   Again, right now I'm new to the world of tuning, so I have no idea...  Post #: 1

As for teh VIN  number, I have never heard of that.  All you really need to do is pop the hood, look what your engine is and thats that.  Then just go to eBay and type in "98 Accord EX headers" and you should find what your looking for. _____________________________ Scopin out my old turf......
