Awe cats, X51 headers and Fister Exhaust (07 C4s) install help in the GTA
#2
Just did it myself. Put on headers to mufflers in my garage with car up on wooden 4x4's. Great writeup on header install by first911 and great writeup on muffler/cats install by utkinpol; both here on this site. Its not too hard if you follow the write up's closely. I used PB blaster overnight to loosen all the bolts. Got all the bolts loosened in one night then rested. Pulled everything off in one night then did the install in one night. The only tricky part is the cats install. I would follow utkinpol's advice about removing the air box so you can get more slack by unclipping the O2 sensors. Gettingn these on and off was the hardest part even with the additional slack; nearly impossible if no slack. Hope this helps. Make sure to wear goggles so you dont get crap in your eyes. Helpful to have someone else but I was able to do it solo with not too much trouble.
