why this one — cp-e's own product page claims about a 5% power gain through the RPM band, but that is a percentage claim from the manufacturer, not an independent dyno number.
Aftermarket catalytic converter downpipe. No CARB-legal statement found either way as of this research pass; verify state emissions compliance (especially CA) with counsel before listing.
Gain shown is a manufacturer claim, not a guarantee. Price is a list price and can lag the retailer; confirm at checkout. See our affiliate disclosure.
