CORSA 3.0" AXLE-BACK EXHAUST
2024-2026 Mustang GT S650 · 5.0L Coyote V8 · Non-Active · Straight-Cut Tips
Hear it — CORSA Sport & Touring on the 2024+ Mustang GT
WHAT THIS DOES
CORSA's 3.0" axle-back bolts straight to the factory resonated mid-pipe on your 2024-2026 GT — no cutting. The custom-tuned, straight-through mufflers wake up the Coyote V8 with a moderately aggressive note about 8 dB louder than stock: heads turn at cold start and under throttle, while the cabin stays drone-free at cruise thanks to CORSA's No-DRONE RSC® tuning.
The straight-through design increases exhaust flow by 46%, so it backs up every other mod you bolt on. Choose Sport for the louder, more aggressive setup (-8 lbs vs stock) or Touring to deepen the tone without adding volume (-4 lbs). Want more than Sport? Add CORSA's Double Helixx non-resonated X-pipe to reach the Xtreme sound level.
WHAT IT'S MADE OF
Full 304 stainless steel — straight-through mufflers and 4.5" dual-wall stainless tips in polished or black PVD. Dual rear-exit layout, direct bolt-on to the factory hangers. Engineered and built in Berea, Ohio, and backed by CORSA's Lifetime Warranty.
TIP OPTIONS
This is the Straight-Cut tip system (PN 21253 Sport / 21257 Touring) — choose Polished or Black PVD above. CORSA builds this same axle-back with Pro-Series Slash-Cut tips (PN 21252) and offers Carbon Fiber tips. Add the Double Helixx X-pipe for Xtreme sound. Message us for any configuration that isn't listed.
