Another customer’s Toyota GR Supra A90 in for one of our Whifbitz 3.5″ stainless steel exhausts along with an OPF delete harness to keep the ecu happy.
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.
Available to purchase on our website here , our exhaust is also available in titanium if you want it super lightweight.
