Invidia Exhaust Systems are among the elite performance exhausts available in the market today. The high-performance exhaust is engineered to maximize horsepower and torque gains. It is constructed of SUS-304 fully polished stainless steel from the cat-back to the canister and features a 101mm tip. Engineered with advanced technology, Invidia uses computerized mandrel-bent to give the exhaust the straightest possible line from the cat-back to the tip with the least amount of bends, CNC machine flanges for strong solid support, and robot TIG weld for strength and durability. Each exhaust system comes with a removable inner silencer to reduce noise levels.
