First check for voltage drop to esdure there are no faults in the wiring from the battery to the alternator. This can be done by touching your DMM on the battery + terminal and alternator + terminal with the engine running. Doesn't matter which way you hook up the neg.pos for the DMM, but you want to go from pos batt to pos alt.. have your DMM set to volts. You should read below .2v for a low resistance lead.
Then, measure your battery terminals with everything hooked up. A typical battery is just under 12v when the ignition is off, so when idling, this should be a few volts higher (13.8v-14.4v) if you can read anything over 12v, your alternator is working. If you get fluctating readings above and below 12v, then your alternator is failing, but typically they are working or not.

^^ good explanation there dirty. you can also load test with the DMM on the pos and neg battery terms and have some one turn on your headlights. your battery voltage might drop momentarily, but if it doesn't come back up rather quickly your looking at a dead alt or one near it's way out.

Ohh the woes of modding....lol
p0174 could cause rough idling. Some possibilities include but are not limited to(man that sounds so commercialized..lol) dirty IAT sensor, coolant temp sensor, 02 sensor, your exhaust like you stated.
I would hook up your exhaust and get that taken care of unlesss you need to bring it down to a shop for welding?
You can test your 02 sensors as well. Read the resistive elements within the sensor to detect it's faults.
Cleaning your IAT isn't hard. You can chec your temp sensor as well, unplug it and read the resistance across the terminals as the engine gets warm. You'll prob set off a code unplugging it though. No biggie.
