In order to provide the most effective and efficient performance solution for the GT4 RS, we opted not to offer a catted header replacement, but instead provide a modular Over Axle Pipe with a catalytic converter. As a standalone piece, our Sport Cat Over Axle Pipe with high-flow cats will deliver tangible sound and performance gains as it replaces the empty particulate filter on the factory units, and paired with our Competition Headers it is a remarkable increase while still retaining a monitored catalytic converter for emissions concerns.

To combat excess heat from the cat core, each of our Sport Cat Over Axle Pipes will include Jet-Hot ceramic coating as standard.

DETAILS:
+ Fits 718 GT4 RS / Spyder RS with factory or upgraded headers or rear exhaust
+ Weighs 6.3 lbs / 2.86 kg less than factory OAPs (18.7 lbs vs 25 lbs factory)
