Overview

The Spec-D Tuning cat-back exhaust system is a 3-inch dual exhaust designed for Ford Mustang EcoBoost models.
Show original supplier description
The Spec-D Tuning 3" Dual Cat-Back Exhaust System is engineered to unleash the performance potential of your Ford Mustang EcoBoost. Designed for 2015-2020 Mustang 2.3L EcoBoost models, this system delivers a significant upgrade in sound and power. Constructed from premium stainless steel, this exhaust system is built for long-term durability and resistance to corrosion. The mandrel-bent tubing ensures optimal exhaust gas flow, contributing to increased horsepower and torque. The system is finished with stylish burnt tips, adding a custom aesthetic to your vehicle's rear. Installation is described as a direct bolt-on process. However, specific fitment applies: it is compatible with 2015-2020 Ford Mustang 2.3L EcoBoost and Ecoboost Premium models. Additionally, for 2020-2021 models, it fits only the 2.3L engine without the Performance Package and without dual exhaust tips. Please verify compatibility with your specific vehicle configuration before purchase.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
