Has anyone tried running open header WITHOUT the collector on? I mean it would be just like running zoomies "sort of" but exiting under the car instead. Anyone tried this before? I thought I saw a supercharged car once that basically had a flat collector that was so short they were zoomies. Is it worth any power or does it hurt power/torque?

They make a 4 into 1 flat collector
for ground clearance.
I believe it would hurt torque production
in an application as you are asking but dont
know for sure.
I have had a collector come off and it hurt et.
