LS1, LS6, LS2, LT1 & TPI Bolt On Parts Guide - The Best Budget Bolt-Ons For Under $800

Hooker Headers
Headers should definitely be in the must-have category for bolt-ons. Gen III mills can pick up gains of 20 rwhp or more from the addition of a good set of long-tube headers. It's hard to beat the bang-for-buck of some uncoated Hooker long-tube headers. Headers can take awhile to install, but most DIY'ers can knock out a set in an afternoon.

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 enjoy some hookage. 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.

Random Technology Catback
Most catbacks will free up some horsepower, 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 Random Technology catback features the best of both worlds: great price and great gains.

HP Tuners Software Package
Tuning options have come a long way over the last 10 years, and HP Tuners is a great option for the enthusiast who is prepared to do some research on how to best tune their vehicle. Being able to turn on your fans sooner, adjust air/fuel ratios, timing tables, and minimize torque management are just a few of the handy features of tuning software. In most Gen IIIs, horsepower gains are easily 10 rwhp to 20 rwhp depending on what other mods you have done to your car. Take precaution and do research before you start programming, since it's easy to get carried away. Saving a copy of your stock program is the first order of business.
