2004 Pontiac GTO Performance Exhaust Products

The MagnaFlow 2004 Pontiac GTO Street Series Cat-Back Performance Exhaust System brings out the personality of your 5.7L 2004-2004 Pontiac GTO with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 2.5in. main piping and 2 Straight-Through mufflers ending in a Dual Straight Driver Side Rear exit with 3in. Polished Welded-On Double Wall Angle Cut Rolled Edge tips, this Pontiac GTO exhaust kit has the performance chops to match its sporty sound and appearance. Upgrade your ride to the next level with an exhaust that has the pipes to put other Pontiac GTO’s to shame. With this system your vehicle will be producing Moderate exterior and Mild interior sound levels while leaving other cars and trucks feeling envious at every stoplight. Exhaust kit 15868 features a cat-back layout that replaces your ride’s stock exhaust components from near the catalytic converter on back. Extensive 3D scanning during development has resulted in a direct-fit design that you can easily install yourself. 15868 is produced using CNC precision robotic manufacturing techniques and is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.

Product Features:

• Dyno-proven performance
• Durable corrosion-resistant stainless steel construction

Fel-Pro Performance Gaskets deliver reliable sealing under grueling racing conditions

Product Features:

• Performance exhaust header gasket consisting of a high-density fiber facing material attached to both sides of a perforated steel core.
• Resists blowout and burnout from high-temperature exhaust and is far stronger than basic paper gaskets.
• Anti-stick coating permits motion without damaging the gasket and makes it easier to remove the gasket for future engine service.
• Slotted bolt holes allow for easier header installation.
• Not intended for use in emission controlled vehicles.

Manufactured from high-temperature steel core/graphite faced exhaust material. Expanded steel core provides stability and maximum torque retention to eliminate gasket failure. Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head. Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. Can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track use.

Product Features:

• Has A Steel Core With Graphite Facing
• Graphite Facing Has Excellent Thermo-conductivity
• High Recovery Mat Allows For Better Seal Retention
• Can Be Trimmed For Port Modifications
• Expanded Steel Core For Stability
• These Gaskets Have Slotted End Holes

Multi-Layered Steel (MLS) exhaust and header collector gaskets are designed for extreme cylinder pressures produced by high horsepower high compression turbo-charged, supercharged and nitrous oxide injected engines. Manufactured from three stainless steel layers, they resist corrosion, will not burn through or push out and maintain maximum fastener torque retention. Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal extreme exhaust pressures. Total gasket thickness .075 inch. Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.

Product Features:

• Multi Layer Stainless Steel 3-Layers
• Round Port 1.75″ Diameter
• Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.
• Thickness .072″
• Fits GM LS Series Engines 1997-’15
