Would swapping my SLP Mids for PaceSetter Long tubes be worth the time/effort, or no?

I'd say on a dyno max HP would be very close. Long tubes move the torque peak lower in rpm range. The SLP headers are 1 3/4 and are one of the best mid length headers. If you had the typical 1 5/8 mids then long tubes would definitely be better.
