You can see at what RPM the resonator section actually starts to create a pressure drop (power loss). The larger the pressure drop the more power you've lost. However, if there is no noticable pressure differential until say 5000 rpm, your not gaining anything by removing it until you go over 5000 rpm. If your driving to get the best mileage you shouldn't be anywhere near 5k rpm.

Haha, very true! That's good information though, thank you for that bit of wisdom. Much appreciated
You're right, this car pretty much NEVER sees that. It sees 2700-2900rpms maximum, daily and that's on the highway.
Great information though, thank you
