Toyota GR Supra (19-) GPF Back - Non-Resonated - Single Valved

This GR Supra performance exhaust is made in 3" (76.2mm) pipework and fits from the Gasoline Particulate Filter section backwards (GPF-back), replacing the centre and rear sections.

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 to be easily upgradable to a full turbo-back exhaust in the future by purchasing additional sections.

The twin valved system offers a jekyll and hyde personality, with the exhaust valves closed the exhaust is refined - allowing the driver to eat up miles in total tranquillity. Then when you hit the country lanes and unleash the B58, the exhaust valves open, and exhaust gases are split between the rear silencer and rear silencer by-pass, delivering the ultimate audible upgrade whilst keeping the factory gasoline particulate filter and catalytic converter in place. 

GPF Back Test Results:

Sound - Engine at Idle: 65dB (+7dB) - Static 4,000rpm test: 91.7dB (+6.7dB)

Please Note:

The resonated exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version which is a louder option as it excludes the centre silencer and therefore, has a sportier exhaust note.

This 'Valved' exhausts retain 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 single valve setup offers a more subtle change in tones when compared with the twin valve setup. 

All relevant fittings and gaskets are supplied.
