The full breakdown.
2020-2026 Chevrolet Corvette C8 · 6.2L V8 · 3-Inch Mandrel-Bent Cat-Back
What This Does
This is a Race Profile valve-delete system for the mid-engine C8. It removes the factory active exhaust valves and includes electronic valve simulators in the box, so the car runs the new exhaust without throwing a check-engine light.
The result is full-time aggression — MBRP’s most aggressive street tone for the C8 — exiting through a quad rear layout.
What It’s Made Of
Built from T304 stainless steel — MBRP’s ARMOR Pro grade, the most corrosion-resistant build they offer and rated for extreme conditions.
The quad tips are dual-wall: a carbon-fiber outer shell over a mirror-polished T304 stainless inner sleeve. Mandrel-bent 3-inch tubing throughout. Electronic valve simulators are included. Part number S70423CF supersedes the earlier S70403CF.

— Why we stock MBRP
A bolt-on cat-back our customers actually finish in their own garage.
MBRP builds a true bolt-on system — mandrel-bent tubing, factory hanger locations, and every clamp in the box. Most enthusiasts have this on in an afternoon with hand tools. Prefer it done for you? Drop the car at our Thousand Oaks shop and our techs will handle the install and a fitment check.
We sell MBRP because it does what it claims: real sound, real build quality, and a warranty MBRP stands behind. No surprises.
