2020 Ford Mustang GT – 6-Speed Manual • Kooks / Borla Build • Dyno Tuned

Route 61 Classics proudly presents this 2020 Ford Mustang GT Fastback, a modern muscle car that's been tastefully tuned for raw performance and sound. Professionally modified and dyno-tested, this Mustang produces 410 rear-wheel horsepower and 390 lb-ft of torque, verified on McNew's Automotive Dyno (dyno sheet included).

Performance & Tuning

Powered by its 5.0L Ti-VCT Coyote V8, this Mustang remains naturally aspirated but far from stock.
Upgrades include Kooks 1 ¾" Green long-tube headers with high-flow cats, a Borla muffler system, JLT cold air intake, and a custom SCT XCal4 tune from McNew's Automotive. The result is razor-sharp throttle response, instant acceleration, and an unmistakably race-inspired exhaust note that's extremely loud and attention-grabbing.

Despite its aggressive nature, drivability remains excellent thanks to proper tuning and calibration. The 6-speed manual transmission paired with a 3.55 limited-slip rear provides total driver engagement and precise control.

Exterior

Finished in Magnetic Metallic with the factory Black Accent Package and gloss black roof, this Mustang presents a striking, cohesive appearance. The paint retains deep gloss and clean reflections overall; however, the roof shows localized clearcoat blemishes and etching visible under direct light (see photos).
Factory 19" Ebony Black painted aluminum wheels and performance tires complete the aggressive stance.

Interior & Technology

Inside, the Ebony cloth bucket seats remain in excellent condition with minimal wear. The cockpit features:

6-speed manual transmission with short, positive throws

Dual-zone automatic climate control

8.4-inch touchscreen navigation with FordPass Connect™ 4G Wi-Fi

AM/FM/SiriusXM audio with Bluetooth & voice commands

Push-button start and factory gauge cluster

The interior is clean, well-kept, and shows no warning lights or mechanical issues.

Chassis & Undercarriage

The car's undercarriage is clean and solid, showing no rust or leaks. Factory independent rear suspension and 4-wheel disc brakes provide excellent handling and stopping power.
Upgraded exhaust routing and high-flow cats are visible underneath, evidence of the quality build and tuning work.
