The full breakdown.
2020-2023 Chevrolet Corvette C8 Stingray · 6.2L V8 LT2 · Active-Exhaust Valve Simulator Pair
What This Does
When you fit a non-active aftermarket cat-back to a C8 Stingray, the ECU still expects to talk to the factory active-exhaust valves over their control harness. Disconnect them and the car throws a check-engine light.
These valve simulators plug into the factory harness in place of the valves and feed the ECU the exact resistance signature it expects — code-free, plug-and-play, no tuning required. Sold as a pair (one for each side).
What It’s Made Of
Sealed electronic resistor modules in an OE-style harness — pair (one per side). No drilling, no soldering: unplug the OE valve, plug in the simulator. Reversible to stock at any time.

— 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.
