Pretty much sez it all. Which should I do for this month? and why

 

I vote for the pulley for 2 reasons:
1. I noticed more gain from it than ORY
2. ORY made my car raspy as hell from 2000-2500, and it stunk from the hydrocarbons.

I vote for pulleys. If you want some gain, go for the pulleys. If you want to change your exhaust note, go for the ORY.

I've seen pulleys result in 6-11 rwhp.

I've seen results from a before/after dyno with an ORY on a fairly stock car...2 rwhp.
