what do yall think

the evo exhaust is nice and so is the apexi
for a relatively low hp vehicle(under 200) a custom vs. manufactured exhaust will not make a huge difference in power output. The factor with an exhaust is back pressure and velocity. Nobody metalshop or muffler shop is going to measure the velocity of the exhaust coming from the motor, apexi or greddy or hks will. They will measure the velocity at the beginning and then at the end and see how much is lost. They will then try to reduce loss through bends, coating, piping diameter, and length. This will begin to make a huge difference with higher hp motors and forced induction systems. So don't be a moron and say that a custom is as good as anything else. If it was then these companies would not be in business.
