I did want to describe the engine running problem, maybe it's normal? so.. I never had any issues with the trucking turning on and running before I did the exhaust.

truck starts.. after a few cranks... runs a little rough, sputters for a few seconds dies. it did this over and over.. maybe and 10-12 times. periodically I would press the pedal and rev it it some. some times it would stay running, sometimes the pedal pressing would kill it. unplugged MAF, plugged in, no change either way... still dies.

I got frustrated, disconnected ground on the battery, pulled intake and MAF. cleaned MAF with cleaner, cleaned throttle body a little with cleaner. installed everything back and same results. on about the 3rd crank after this, I constantly kept reving the truck with the pedal, about 2000 rpm, up and down. finally it stayed running and idled great.
