How long you think it would take to install the AS&M headers on a 4.8. Trying to figure out what it's going to cost me for installation

 

4 hours max with the proper tools. The cut can be made 1/4" infront of the cats and the reast of the pipe and stock manifold can come out together. That's what I did. It took me about 6 hours and I had to use a manual tailpipe cutter!

yep, headers are a really easy install

should take anywhere from 3-8 hours depending on tools, knowledge, and the ammount of <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" /> involved. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

has anyone had trouble with the bolts stripping or the heli coils coming out. what is the torque #'s for these

not positive but i believe its somewhere around 18-22 ft/lbs. i didnt have a problem with it though. sprayed some liquid wrench on there and they came off easy <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I had a sawzall and it still took me 7 hours! I used hand tools for everything else. Air tools would help a lot! Install is straightforward. Everything fits well. Just gotta weld the flanges on to the cats. Use the stock gaskets, they work fine. However, ASM do give you OEM gaskets so you can't go wrong there. The best is when you fire up that engine with the headers uncapped <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . One last thing...try not to take too many <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> breaks. Maybe that's why it took me 7 hours <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" /> .

 

the headers have some kind of caps...or what?

 

He meant that it sounds like you have a cut out right behind the headers.
