Custom exhaust help

To change the plugs the headers actually unbolt and pop out very easy. I will be using some heat wrap and getting some protection for the plug wires, they're in there temporarily now 9just had to hear it run). Haven't gotten to the underside yet, but looks like a lot of clearance, when it's done I'll get some pics of the underside. Seems like a logical place to mount the alternator with no power steering, to much stuff on the passenger side.
