I finally got around and spent Saturday and installed my Mac long tube headers along with a mac prochamber mid pipe. The are ran through a magnaflow catback with dumps. The sound is not that much louder than it was before at idle but you get some more sound when you get into it. As far as install I already had a UPR k member And it made the install pretty easy. The upr k member was worth every penny just for the sheer fact you can get to everything, starter was cake! The drivers side header went right in with no problems what so ever, the pass side, since I used factory hardware I had to remove most of the exhaust manifold studs to get it in but really wasn't that big of deal. The pass side header was the only one that barely touched the firewall a little. The mid pipe lined up fine and bolted right up without issues to the rest of the exhaust. I will say if you buy the SR performance 02 extensions the do not plug right in, I had to cut the tabs off of the plug ins to get the to snap together. While I was at it I installed an aeroforce wide band, that was pretty straight forward. I would recommend the headers to any one! Now the killer chiller, I thought it would be a little easier to install than it was but still not to bad. Really the hardest part was to cut the bumper absorber to fit the killer chiller. I'm sure I cut alittle more than I needed to but I wanted to make sure none of the lines showed through the front bumper. Another issue I had was that on the killer chiller itself the fittings for the AC lined where so close to the other lines coming out that It was hard to get all the lines on. I have looked at other peoples install and most of the units I see the killer chiller itself is longer and the fittings are not as close together. Stupid me did not get any pictures of It once I had it all in. It was getting late and I just wanted to be done! I will get the AC recharged and post the results. If anyone has any questions on the install I will try to help If I can! All that is left is to get my ported blower, Lower pulley, and Bap installed then to the dyno for a tune!!
