I think after the crossover (H-pipe) i'm going to hike up the pipe size to 3" all the way back still... i hope it works out for me. ^__^
It's only a 3.0L NA motor. Big diameter exhaust isn't worth it. Plus, if you compare diameter, dual 2.25" has more area than a single 3". Dual 2.5" is just to much for this motor. I'm going with 2.25" to keep the exhaust velocity high thus keeping the torque and hopefully gaining some power.
