ZZPerformance Power Logs

Compared to more complex exhaust modifications like headers, ZZPerformance power logs offer a cost-effective way to improve exhaust flow and performance. ZZP's power logs offer several benefits, including increased engine performance, improved efficiency, and enhanced safety. They eliminate the restrictive manifold and U-bend, reducing backpressure and improving exhaust flow, which can lead to a noticeable performance boost, especially when paired with other performance upgrades like downpipes. Additionally, power logs can also help lower knock-related issues and keep the engine cooler due to the reduced exhaust restriction. Select the ZZPerformance power logs designed for your application needs.

ZZPerformance Modular Supercharger Pulleys

ZZPerformance offers modular supercharger pulleys for a variety of applications, including 2004-05 Buick, Chevy, and Pontiac engines. The aluminum pulleys are available in a range of outside diameters, with a black or clearcoat finish. Each pulley system includes hub, pulley of your choice, five stainless socket cap button screws, and one barbed retainer to replace the breather bolt. After removing the stock pulley, the ZZP steel hub presses on using the same pulley tool used to remove the factory pulley. No jaw-style puller should be used to remove a supercharger pulley. If it is used, it will destroy the pulley and possibly damage the supercharger. Once installed, the hub allows quick-changing of pulleys with an Allen wrench. The ZZP modular pulley system (MPS) allows you to change between pulleys depending on conditions; use one pulley for street use and a smaller for the track or when running high octane fuel. An MPS is a must for those planning to continue to modify their car in the future. ZZPerformance pulleys come with eight ribs on them, but a 6-rib belt will still work completely fine. * Fits: -- Pontiac Grand Prix GTP or 06+ GT -- Buick Regal GS -- Pontiac Bonneville SSEi -- 2004+ Impala SS -- 2004+ Monte Carlo SS * Pulley recommendations: -- 3.5 pulley for 01-03 GTP/GS with ZZP PCM, Tstat, colder plugs, bolt in downpipe, and a cold air intake -- 3.5 in. for 2004+ Grand Prix recommended for cars with 1.9 rockers, Tstat, colder plugs, some exhaust work, and a cold air intake -- 3.4 in. for 1997-2000 GTP/GS with ZZP PCM, Tstat, colder plugs, bolt in downpipe, and a cold air intake -- 3.3 in. pulley requires a small cam or headers or any SS intercooler -- 3.2 in. pulley requires a XP cam or a SS intercooler with 1.9 rockers -- 3.0 in. pulley requires larger injectors and a full-size intercooler -- 2.8 in. pulley requires a cam, intercooler, and headers

ZZPerformance Mid-Pipes

ZZPerformance mid-pipes are a relatively inexpensive upgrade compared to full exhaust systems, while still providing a noticeable improvement in power and exhaust note. That makes them a good choice for those looking to enhance their car's performance without breaking the bank. By removing the restrictive factory catalytic converters or other components, mid-pipes allow for easier exhaust flow which leads to better performance. The change in exhaust flow can create a more aggressive and satisfying exhaust sound. Mid-pipes are also generally easier to install than full exhaust systems, offering a good balance of the benefits of performance gains and ease of installation. Select the mid-pipes in the application that's best suited for your exhaust system setup.
