If your looking for power, adding a glasspack will drop your torque. You need SOME backpressure.
If I had the choice between the Exhaust or an Electric Fan, It would be for the fan ( I have both Already ).
Your going to want a Fan that can toss 2800cfm's ( roughly ). Theres several Vendors on this site that carry them, all have been proven reliable.
The electric fan will remove a parasitic loss from your engine. You won't ' gain ' power, you will re-coup whats been taken away from it ( It was already there ). This will cause less of a load on the motor which gives you better econemy and frankly.. less wear.
The ONLY downside to an electric fan is teh Electrical draw. On average, I see a 20-22 Amp draw. I replaced/upgraded to a higher rated altenator. I havbe MANY electrical ' gizmos ' running in my truck via Neons, Solonoids, relays.. So I needed to upgrade without the fan before hand.
You can wire the fan for manual turn-on , to the A/C relay or even a Therma switch in your radiator ( however you choose. Mine has both thermal and manual capacities ).
