Which brand header is the best?

Chryco got more torque out of a single exhaust, even on a 273 commando.
:thumblef: I am running 2 2'' to a single 2 1/4'' then back down to a 2'' at the tail pipe like I was advised to and I agree it needs the right amount of back pressure :thumblef:

Yes :glasses7: I remember uncapping my headers just to loss a full second in the 1/8 mile pishta :thumblef:
