DESCRIPTION
Maximize High-RPM Flow. Eliminate Backpressure. Transform Your Miata's Performance.
Unlock the full high-revving potential of your Mazda MX-5 ND 1.5L with this Premium 4-1 Performance Race Exhaust Header. Purpose-built for track enthusiasts and performance tuners, this header deletes the restrictive factory catalytic converter in favor of an unrestrictive, straight-through design. By utilizing a high-efficiency 4-into-1 merge collector, it minimizes exhaust backpressure, radically accelerates exhaust gas scavenging, and sharpens throttle response to deliver substantial power gains across the upper powerband, complete with a crisp, raw racing roar.
