Hey I'm in the process of installing 3" catted downpipe on my 04 impala ss, right now I'm just soaking the bolts down for a few days with pb blaster. anyways the two bolts in the back look difficult to remove and to remove the stock downpipe looks hard. Is there any write up's or a printable instructions for this ? Thanks a lot! By the way I also bought a wizaired cai, tuned pcm, autolite 103 plugs and a 3.5 pulley, I had to drive it home with only the tune pcm, 3.5 pulley and cai, the mechanic was confused with the downpipe and didn't have time for the plog and spark plugs, was it a bad idea driving it home (20miles) ? I didn't make any boost I babied it home.
