I did glasspacks last week- unhappy with it and going with magnaflow + glasspacks this week . Where is it that they are $39? As far as burning out...the things cost 10-15 bucks (glasspacks) no big loss there. It might be possible to put a glasspack in the res spot and have pipe run back to the back. I am trying that while I look for a magnaflow I can afford.
