Xtreme Sound Level
CORSA's Xtreme configuration is designed for F-150 owners who want the most aggressive sound available for this application. It produces a noticeably stronger exhaust note than the Sport system on both cold start and under acceleration, giving the 5.0L V8 a more commanding character while introducing only slightly more in-cabin volume.
Single Side Exit Design
The 21145 uses a single side exit configuration for a clean, performance-oriented appearance. The 3.0-inch Cat-Back system routes the exhaust to one side of the truck and finishes with twin 4.0-inch Pro-Series tips, creating a compact and aggressive setup that complements the Xtreme sound profile.
Black PVD 4.0-Inch Pro-Series Tips
Twin Black PVD 4.0-inch Pro-Series exhaust tips provide a dark, aggressive finishing touch to the single-side exit system. Each tip features dual-wall stainless steel construction with a slash-cut design, combining durable construction with a stealthier appearance than traditional polished stainless steel.
Weight Savings
The Xtreme 21145 system saves approximately 25 pounds compared to the factory exhaust. This reduction in exhaust system weight adds another performance-focused benefit to the louder sound and more aggressive side-exit styling.
