Pulling the rear section doesn't really help unless the rest of the system is less restrictive too. The stock exhaust system was designed to work with the stock induction system. If you have an intake, that frees up some flow restriction right there, and so pulling the rear section is going to accentuate that increase in flow all the way through the system. Keep in mind that you are not going to see a breth taking increase in power. If you notice any at all, it will be in the top end. MOst stock honda exhaust systems are tuned to help out in the midrange, where every honda is lacking.
