Thanks
Yes 100% test pipes will be louder over HFCs, but you'll also gain a few HP. FI HFCs you have everything running through a 300 cell cat...where with a test pipe, its running straiiiiight through. There's nothing resisting it at all.

Resonators have nothing to do with performance, only sound. They won't take away HP, but will help avoid rasp and drone.
