Product details
The MagnaFlow Toyota GR Corolla NEO Series Cat-Back Performance Exhaust System #19631 turns your ultimate sporty compact into a JDM-like beast that stays at the head of the pack thanks to its modern take on MagnaFlow’s signature sound and renowned dyno-proven power gains. This GR Corolla exhaust kit represents an all-around performance improvement for your GR’s 1.6L without compromises, even going so far as to retain your OEM vehicle’s factory controllable exhaust valve option using MagnaFlow’s own cast 304 stainless steel valves. Additionally, #19631 seamlessly integrates MagnaFlow’s No Drone Technology (NDT) to ensure optimal driver enjoyment, free of any unwanted droning noises that can otherwise occur at cruising speeds. Exhaust kit #19631 features 3” mandrel bent main piping that passes through an 11” NDT tuned chamber, smooth Y-pipe transition and two 11” straight-through performance mufflers before terminating in a quad center split rear exit with 4.5” outer and 3.375” inner tips featuring a double wall, angle-cut logo etched design with a black chrome finish. This performance exhaust features an easy-to-install, direct-fit design that is engineered to replace all OEM exhaust components from near the catalytic converter on back. #19631 is made of durable, corrosion resistant stainless steel and produced using advanced CNC precision robotic manufacturing techniques, all backed by MagnaFlow’s limited lifetime warranty.
