Roush Y-Pipe Resonator Delete
Replace the restrictive factory exhaust resonator with this 2015-2024 Mustang 2.3 Y-pipe resonator delete! From the factory, your Mustang has a large, restrictive resonator in the middle of the catback section of your exhaust to quiet things down. Roush designed this resonator delete to free up exhaust flow and sound while eliminating unnecessary weight. The Y design provides an exotic tone that's sure to turn heads. All of this is achieved without triggering a check engine light and installs easily with a cut and clamp design!

Corrosion-resistant stainless steel is utilized to ensure long-lasting performance for years to come!
