Borla Touring Cat-Back Exhaust System with Polished Tips (140081) - 2003 Ford Thunderbird 3.9L V8
Wake up the high-performance spirit of your luxury cruiser with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered exclusively for the 2003 Ford Thunderbird, this premium full-length exhaust upgrade introduces Borla's most refined acoustic profile: the Touring sound level. Formulated explicitly for driving purists and luxury car enthusiasts who crave a clean, smooth, and mature exhaust note rather than an overbearing or loud bark, the Touring muffler configuration is calibrated to give the 3.9L V8 engine a sophisticated, deeper-than-stock tone under acceleration. This cat-back configuration provides just the right amount of performance presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely quiet and drone-free during highway cruising, daily commuting, or weekend road trips with the top down.
The internal engineering of the Borla 140081 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.25-inch diameter inlet piping that steps smoothly into 2-inch tailpipes. This system utilizes ultra-smooth mandrel bends to optimize exhaust velocity, maximize gas flow, and unlock hidden horsepower, throttle response, and enhanced fuel economy across the entire powerband. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a distinctive single split rear configuration featuring large 4-inch round, rolled angle-cut lined mirror-polished T-304 stainless steel tips. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla's legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the iconic 2003 Ford Thunderbird retro-bird platform powered by the 3.9L DOHC V8 engine. It is fully compatible with the factory 5-speed Automatic transmission and fits 2-Door Coupe and Convertible Rear-Wheel Drive (RWD) models. It is not designed to fit alternative model years such as 2002 or 2004-2005 variations without potential mid-pipe modifications due to factory oxygen sensor or catalyst position adjustments.
