Hooker Catback
Most catbacks will help you net about 15 rwhp, and give you a kick-butt sound to boot. While the power gain is mostly from running a lower-restriction muffler, going from 2.75-inch exhaust to 3 or more helps out too. Most DIY'ers can swap out a catback in a couple of hours, or longer if you try to take it out in one piece. The Hooker catback is the best of both worlds-great price and great gains.

Crane 1.6 Roller Rockers
Swapping out the stock, stamped, 1.5 OEM rockers for a set of Crane self-aligning rocker arms is done for several reasons, however, the gain of 5-7 rwhp is why LT1 enthusiasts routinely suggest this swap as one of the must-dos. The other top reason is for increased valvetrain stability when turning the engines at higher rpm.

Meziere Electric Water Pump
Even though stock water pumps are efficient, electric water pumps are still worth over a tenth at the track and some measurable ponies on the dyno. Veteran DIY'ers will typically wire the pump to keyed ignition since most of us would probably forget to turn the pump on until after the car has overheated. Or, if you prefer, wire it to have the pump triggered manually to cool the engine down after making a pass without running the engine. While not a hard install, the wiring takes some skill.
| Price: | $219 |
| Gain: | 8 rwhp |
| Performance: | .05 e.t. reduction and 1 mph gain |
| Install difficulty: | Hard, since there is wiring involved |
Nitto Or Mickey Thompson Drag Radials
Traction is the name of the game with drag radials. Air down the tires according to the manufacturer's guidelines, do a good burnout, and have your head snapped back. Nittos work well for cars that see a lot of daily driver miles, and will last longer. The Mickey Thompson drag radials will wear out a lot faster but will out hook all other drag radials.
| Price: | $400 for two |
| Gain: | N/A |
| Performance: | .3 e.t. reduction and 1 mph gain |
| Install difficulty: | Easy for the tire guy |
