Borla 140840BC Cat-Back Exhaust System Kit for C8 Corvette with AFM/DFM Valves

The Borla 140840BC Cat-Back Exhaust System is engineered specifically for the C8 Corvette, delivering the S-Type sound level that provides a powerful, deep tone with a perfectly balanced exhaust note. This system offers an exciting driving experience with zero drone, making it ideal for both spirited driving and daily commuting.

• S-Type Sound Level: Delivers aggressive performance tone without cabin drone

System Specifications:

• 3-inch inlet diameter for optimal flow
• Includes AFM (2020-2021) and DFM (2022-2025) valves
• Does NOT include NPP dual mode exhaust valves
• 4-inch round black chrome on T-304 stainless steel tips
