Cobra Sport Porsche Boxster/Cayman S/GTS 2.5 718 GPF-Back Exhaust System
Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.
This Porsche 718 Cat/GPF back performance exhaust is made in 2.5" (63.5mm) pipework and fit from the Catalyst/Gasoline Particulate Filter section backwards (Cat/GPF-back), this exhaust replaces the link pipes and rear sections.
Featuring a resonated option which accentuates the tone and burble of the boxer engine without being overly loud, and a non-resonated version which gives this performance car the performance sound that you would have expected direct from Porsche.
With a choice of 4" tailpipe options including carbon fibre tips, this exhaust offers improvement in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place.
This exhaust system has been designed with interchangeable options, allowing the user to tailor the system to their needs using the drop down boxes. The utilisation of V-bands means that you can easily swap out the resonated section for non-resonated or vice versa at a later date, just contact us and we can supply the relevent part at a fraction of the cost of the full system.
Please Note:
All relevant fittings and gaskets are supplied.
The valved system is only compatible with vehicles enabled with PSE from factory.
