headers

Yes, if you get longtubes, you have to get the matching h or x pipe. You can put equal length shorties or unequal length shorties in place of the factory headers. If you are going to buy headers, might as well upgrade the rest of the exhaust system too. If you don't have to do emissions inspections, you can put a off road h pipe or x pipe. The h pipe is a little louder at idle speeds, but in the high rpms, they are about the same. The main thing in the sound category will be the after cat muffler choice. Most popular ones are flowmaster 2 and 3 chambers. But they all sound good. Go here and listen for a good comparison. IMO, I would get some longtubes with a matching o/r x pipe, with any performance muffler. I doubt you would regret any selection you make.

Oh yeah, the h/x pipe is the pipe that goes from the headers to the mufflers. You will not have to have anything special made.
