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

Under $500

SLP Cold-Air Induction
Look no further than SLP for a great cold-air system. SLP designed this system for maximum performance by creating a more direct air path, and including a better-breathing, cotton-gauze air filter.

Hooker Super Comp Long-Tube Headers
While there are many options for the tuned port injection crowd, the Hooker long-tube headers provide the best overall horsepower gains as well as a substantial increase in torque. These headers are available coated and uncoated-the uncoated ones will cost less than $200.

Hooker Catback
Hooker exhaust systems are 100% mandrel bent and built to their high standards. This system utilizes their Aero Chamber mufflers, which provide major horsepower gains and a deep, powerful sound. This system gets the nod based on the gains and best average price.

MSD Ignition
While more of a supporting cast member in this ensemble, the venerable MSD ignition system increases spark, improves combustion, and improves throttle response for most TPI combinations. While spending upwards of $300 on an ignition box and a coil does not seem like a direct value, these mods are typically needed to support the TPI rodder's quest for e.t.'s in the 11s and 12s.

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, though the gain of 5-7 rwhp is why TPI enthusiasts routinely suggest this swap as one of the must-dos. Stock rockers are now 20 years old and were never designed for higher performance levels.
