2018-2026 Ford Mustang GT & Dark Horse | 5.0L Coyote V8 | Borla Cat-Back Upgrade
2.75″
3″
T-304 Stainless Steel
Hydroformed SwitchFire
This is an X-Pipe upgrade for owners who already have a Borla cat-back system. Replaces the standard Merge X-Pipe with Borla’s patented SwitchFire design. The SwitchFire eliminates the turbulent center intersection of a standard X-Pipe, blending combustion pulses from both banks for more aggressive sound and improved flow. Hydroformed for a lower profile than conventional X-Pipes.
NOTE: Only works with Borla 3″ Cat-Back systems — not compatible with stock or other aftermarket exhaust.
T-304 stainless steel — not the T-409 that cheaper brands use. Won’t rust, pit, or discolor. Hydroformed center section provides a lower profile than conventional X-Pipes while maintaining optimal flow geometry. Made in the USA. Ships at 11 lbs — 33 x 9 x 9 in. (boxed).
