GPF Back with Box Delete Test Results
Sound - Engine at Idle: 73.5dB (+10.5dB) - Static 3,800rpm test: 95.1dB (+13.1dB)
All relevant fittings and gaskets are supplied.
This exhaust offers a significant improvement in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place.
This exhaust has a choice of 4" (101.6mm) tailpipe options including a choice of carbon fibre tip options.
The 'Valved' exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will continue to swap from quieter to louder tones as before.
The 'Non-Valved' exhaust removes the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however, the Cobra Sport exhaust has been designed with this in mind.
