well i finally had my emissions test and passed so im installing my magnaflow o/r x and the magnapack catback as soon as i see a sunny day. The question i have is about taking the stock exhaust off. In my installation guide from magnaflow it says i have to cut the stock exhaust behing the exhaust tips and a few other places. Is cutting the stock exhaust neccessary? and if so how easy is it to put back together?
