Frenchtown Flyer, what is it you disagree with? I'm always open to seeing another point of view. If you disagree, please explain why so I and others can understand.

Also, my post was about overall drive quality, not achieving the fastest quarter mile. The original post was about his ability to pull hills, generally a lower RPM torque situation, not a high RPM race situation. When you are only considering speed or overall acceleration, like 1/4 mile times, low RPM scavenging isn't even at play. You never spend time in the rpm range where it's important. I'm not saying you will have faster 1/4 mile times with a more restrictive exhaust, it'll never be the case. I'm talking about overall driveability, being able to pull hills and have a nice idle and leave stop signs without reving to 3000 rpms.

Everyone should understand the difference between driveability and overall performance. Once generally detracts from the other, especially when fuel injection is not present.
