shouldnt be any unknown probs at all. its a basic swap and pretty easy mod. just kinda hard to get to those bolts in the back. good luck

since their shorties I believe they should be pretty easy, now if they were LT some people have problems with them. good luck on the install

we have a tech article for ASM install on NBS trucks at www.getonitracing.net It will be up by friday. for any further questions pm me

and watch out for the bolt on the steering shaft. it may get in the way so you may want to switch to a smaller bolt!

Hey guys?...As far as cat-back systems w/ the headers goes. They come with the 02' Sensors correct. I cnat remember where there located but when just changeing the headers, they wont trip a 02' sensor code will they?

Blake @ FMS

it depends, if you put on long tubes and drive to your local shop to have the exhaust weled on the headers,yes. if you install shorties then they shouldnt effect the o2's at all. The o2 sims are before the cat and right after the cat. ON EC trucks the sensor behind the cat on the passenger side is kinda far back but you'll find it.
