Good idea or not? Would the shortys still help over stock headers if the car is supercharged (say to about 460-500 flywheel)? Or would too much back pressure be a problem? I don't want to choke the system. Or is it safer to go supercharger with stock headers? Does a shorty header allow more airflow than stock, thereby making it easier on the boost? I know long tubes can be great for a supercharger though? But I lowered the car like 2" already and long tubes might not fit. Help please!
