BORLA 140135 Cat Back Exhaust System MUST GT 05 4.6L V8 AT / MT RWD

Description BORLA 140135 Cat Back Exhaust System MUST GT 05 4.6L V8 AT / MT RWD

For over four decades, BORLA Exhaust has been a choice among Mustang experts. Major players in the racing industry and leading tuners, including Roush, Steeda, Saleen, Ford Racing, and the Shelby 427 Cobra, have relied on BORLA. This 2.5" diameter Cat-Back system bolts behind the factory H-pipe and is lighter than the factory system.

BORLA's experience and advanced engineering have produced the classic "S-Type" exhaust with outstanding flow numbers, generating power enhancements without interior drone. The system features large single 4" round chrome on T-304 stainless steel tips on each muffler assembly. The unique muffler and exhaust configuration cancels additional high frequency sound waves.

This system delivers a significant increase in exhaust flow CFM over the factory system, which contributes to notable power improvements. The added flow also maximizes performance for other aftermarket enhancements installed on the Mustang, as all BORLA exhaust products are tuned for maximum output from any performance upgrade. Two Axle-Back system options are also available: the classic "S"-Type (PN 11750) and a more mellow Touring (PN 11752), both replacing only the over-the-axle pipes, mufflers, and tips.
