I won't have back to back comparison but Sound Performance will be dumping my car with the FSR manifold next week most likely so we can compare with my steed speed setup as the only major engine mod I changed is the exhaust manifold so the dynos should show a decent comparison

Whats the spool difference?

Power difference?

HPF manifold is a semi-tubular desing, FSR is a complete tubular design. I am curious.
