Don't go into NASIOC asking this, at least take out the consideration for OBX because you'll get flamed.
Consider a 2.5'' V-Band if you want more emission friendly, or 3'' if you're needing more power.
The torque increase from the downpipe is pretty worth it, but like the others said, get both and tuned or none at all.
You are an idiot
