I found out today when I was installing my H&R springs that my muffler is almost completely rusted through, and the B-pipe isn't to much better. I was thinking about going to the local muffler shop and getting them to make me a 2.5" B-pipe and just put a normal muffler on there. If anyone has done this I would really like to know how this turned out, because if that doesn't work I'm going with the Apex'i exhaust, any info would be helpfull. Thanks
