Garage Whifbitz 3" titanium twin box exhaust for the Toyota Supra JZA80. Made from super lightweight titanium these are as light as a feather, this twin box version weighing in at only 6.4kg. Having 2 boxes makes this a quieter option than the single box version, for those wanting to use the car on track days this is ideal. They not only look good with there beautiful burnt tip apperance but also increase performance from the engine and by giving you a better power to weigh ratio over a stainless steel exhaust. These are designed for cars running up to around 750bhp giving a fantastic noise. 4" is recommended for anything above this. Benefits include: •  Free flowing design improves power, torque and response over the factory fitted exhaust. •  Titanium being lighter than steel gives your car a better power to weight ratio helping to improve straight line performance and cornering ability. •  Titanium is stronger than steel but lighter so we are able to build an exhaust that takes abuse better than its steel counterparts but with significant weight savings over your typical factory fitted and aftermarket steel exhaust systems. •  Titanium is highly resistant to corrosion, unlike stainless steel exhaust units which may rust or decay over a period of time so long life is guaranteed.
