Garage Whifbitz 3.5″ type 1 stainless steel exhaust for the GR Toyota Supra A90.
Made from high quality 304R stainless steel our full exhaust from the cat back removes the restrictive OPF. Dyno tests revealed a 15bhp gain in power and 40 lb/ft gain in torque compared to the OEM exhaust. There will be even more power to be gained on higher horsepower cars when the stock exhaust will become even more restrictive.
3.5″ in diameter from front to back where it splits into 2x 3″ silencers and keeps the exhaust valve so you have the OEM noise control. Made using 3.5″ oval pipework to keep the ground clearance to a maximum without affecting flow.
Noise levels are 90DB at 4000rpm static with the valve open but provides a nice deep exhaust note under full throttle as can be heard in the video below.
Available to fit USA/Rest of the world and European spec vehicle and will fit the 2 litre and 3 litre models.
As the OPF is being removed you will either need an ecu remap or OPF delete harness, both available from us.
Please contact us if you need any information on which version fits your car.
