Slp Off-Road Y-Pipe
Another good bang-for-the-buck would be this Y-pipe, which also eliminates factory catalytic converters. While not emissions legal in most states, this mod is worth some power and will turn heads at the strip.

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

Ls1 Ls6 Ls2 Lt1 Tpi Bolt On Parts Guide Qtp Exhaust Cutout

QTP Exhaust Cutout
For about the cost of three pizzas, you can buy an exhaust cutout such as the QTP. By running an open 'dump' you can free up some horses without spending a lot of money on a catback. You will need to have this cutout welded into your stock exhaust, typically in front of the rear axle.

Price: $45
Gain: 12 rwhp
Performance: .1 e.t. reduction, and 1-2 mph gain
Install difficulty: Hard unless you know how to weld


Under $500

Price: $299
Gain: 8 rwhp
Performance: .05 e.t. reduction and 1 mph gain
Install difficulty: Medium


Ls1 Ls6 Ls2 Lt1 Tpi Bolt On Parts Guide Asp Undercover Pulleys

ASP Underdrive Pulleys
Another tried-and-true bolt-on, the underdrive balancer pulleys free up horsepower while still charging up the factory system just fine. While not too hard to install, hitting the final torque spec will take some muscle unless you are using power tools.

Price: $269
Gain: 8 rwhp
Performance: .05 to .1 e.t. reduction and up to 1 mph gain
Install difficulty: Medium


Ls1 Ls6 Ls2 Lt1 Tpi Bolt On Parts Guide Slp Ram Air

SLP Ram Air
This is one of those mods that shines at the track, though the dyno gains are modest. This induction setup is a killer addition to LS1-powered 4th-gens, and is typically worth nearly a solid tenth and a 1 or more mph gain in the quarter.

Price: $169
Gain: 5 rwhp
Performance: .05 e.t. reduction and 1-2 mph gain
Install difficulty: Easy
