Why Good Headers & Exhaust Systems Matter
At ~85% volumetric efficiency, a 2.4L engine at 4000rpm draws in approximately 4,100L/min and expels around 12,300L/min exhaust gas due to heat expansion. A well-designed header and exhaust system helps move this gas efficiently, reducing restriction and improving scavenging.
Warranty and Compliance
Wildcat headers are covered by a 12 month warranty, subject to the manufacturer's standard warranty terms and conditions.
Exhaust, noise and emissions requirements vary by state, territory and vehicle, so check the rules that apply to your vehicle before fitting.
