Description

The Spec-D Tuning cat-back exhaust system is a performance-focused upgrade for the Ford Mustang 2.3L EcoBoost, utilizing patented straight-through and multi-core technology to optimize exhaust efficiency. Compatibility is specific: this system fits 2015-2020 Ford Mustang 2.3L EcoBoost and EcoBoost Premium models, as well as 2020-2021 Ford Mustang 2.3L models without the Performance Package or dual exhaust tips. It is also compatible with 2015-2023 Ford Mustang EcoBoost Fastback models that are not equipped with the Active Exhaust system. It does NOT fit models equipped with the factory Performance Package, models with factory dual exhaust tips, or models with the Active Exhaust system.
