CORSA 3" Cat-Back Xtreme Exhaust w/ RSC® For Mustang

Turn the Coyote loose. CORSA’s 3" cat-back pairs 304 stainless construction with straight-through, custom-tuned mufflers built for the 5.0. Precision acoustic work plus RSC® No-Drone tech means +16 dB of on-command thunder at cold start and WOT—without the highway headache. Flow for days, tone with teeth.

built to howl, tuned to win.


Why It Hits

  • 3" T304 stainless: welds that last, fitment that doesn’t fight you.

  • Straight-through design: real flow, real gains; ~48% more flow to stack with your other mods.

  • RSC® No-Drone: cabin stays calm at cruise; the bark shows up when you ask for it.

  • Xtreme sound level: aggressive when it should be, civilized when it needs to be.

  • 4.5" dual-wall tips: pick your flavor: slash-cut, straight-cut, or carbon fiber.

  • Made in the USA: built right, backed by a Limited Lifetime Warranty.

Power. No pretend.

What It Fits

  • Ford 5.0L Coyote platforms — most commonly Mustang GT (S550/S650) and select F-150 5.0 applications by part number.

  • Fit varies by chassis, wheelbase/cab (F-150), tip style, and active-exhaust compatibility.

  • Pro move: match your exact part number to your vehicle before checkout. If you’re running factory active valves, verify adapter/compatibility in the kit specs.

Basic Install Overview

Bolt-on cat-back. A lift helps. Penetrating oil and a torque wrench make it painless.

  1. Prep

    • Let the exhaust cool. Disconnect battery if working near valve harnesses.

    • Soak factory clamps/hangers with penetrant. Lay out the CORSA kit in order.

  2. Remove Stock Cat-Back

    • Loosen mid-pipe/clamp connection(s).

    • Unhook the system from rubber isolators (support the weight as you go).

    • Carefully drop the OE cat-back in sections.

  3. Build the New System

    • Slip-fit the front pipe/X-pipe to the mid-pipe connection—snug clamps (don’t fully torque yet).

    • Hang the mufflers on factory rubber isolators.

    • Install tailpipes and position 4.5" dual-wall tips (slash, straight, or carbon) to taste.

  4. Align & Clearance

    • Center tips in the valance, set even depth/angle.

    • Check for driveshaft, brake line, and heat-shield clearance at full droop.

  5. Torque & Test

    • Torque band clamps evenly from front to rear to manufacturer spec.

    • Start the car, check for leaks, let it heat-cycle, then re-torque after a short drive.
