【AS】High Flow Catalytic Downpipe

To comply with emission regulations, the original exhaust manifold uses a dense honeycomb catalytic converter.
While effective at treating exhaust gases, this design also restricts exhaust flow,
leading to excessive back pressure and affecting turbocharger output efficiency.

AutoScience Studio's high-flow catalytic converter downpipe significantly reduces exhaust back pressure while retaining a high-flow metal catalytic converter,
allowing the turbocharger to build boost more quickly,
improving throttle response and mid-range torque, while maintaining basic exhaust gas filtration.

▌ Product Features
