Do you know how big the cam is that you're running? The super comp hookers and 2.5 inch duels sound great. An H-pipe balances out the exhaust system gases and helps with the scavaging effect. It will help you with low end torque. You might not need the 2.5 inch pipes though, 2.25's might be better. What exhaust are you running now? The smaller pipe might increase the exhaust gas velocity more than a big pipe. Because you're running 2v heads your system probably wont flow over 6000RPM's, so the need to run a 2.5 pipe that will flow better at high RPM is not necessary. Just my 2 cents
