MBRP 3" Quad Rear Cat-Back Exhaust w/ Carbon Fiber Tips (S70423CF) – 2020–2026 Chevrolet Corvette C8 6.2L
The MBRP Armor Pro Series 3-inch Cat-Back Exhaust is the ultimate race-oriented exhaust upgrade for the Chevrolet Corvette C8. Built for enthusiasts who demand maximum performance, aggressive sound, and premium materials, this system is constructed entirely from T304 stainless steel and finished with quad carbon fiber tips for a true supercar appearance.
Designed with a full 3-inch mandrel-bent layout and an integrated X-pipe crossover, this system improves exhaust scavenging, throttle response, and overall power delivery. The Race Profile tuning delivers an aggressive, high-performance exhaust note that matches the C8’s mid-engine character while shedding factory restriction.
This system features a valve-delete configuration and includes electronic valve simulators to prevent warning lights on non-NPP equipped vehicles. Welded-on hangers ensure precise fitment, while the quad split rear exit fills the factory bumper openings perfectly for a clean, factory-plus look.
Finished with dual-wall, angle-cut 4.5-inch carbon fiber tips featuring polished T304 stainless inner sleeves, the S70423CF combines durability, heat resistance, and race-inspired styling. Backed by MBRP’s Lifetime Warranty, this is a no-compromise exhaust solution for serious Corvette owners.
