Tomei FULL TITANIUM MID PIPE KIT EXPREME Ti 86/FR-S/BRZ TYPE-80 To truly enjoy the FA20 is to extract the most from it in NA form. So maximum weight reduction is an essential part of it. This product is specifically designed for competition use. With the absence of a catalytic converter, the pipes made from Titanium, this drastically reduces the overall weight to compliment the power gains. When fitted to a car that has a forced induction setup, it greatly enhances the performance gains with the improved exhaust flow efficiency. This is one of the key products to extract the performance potential of the 86/BRZ/FR-S. TYPE-80 features a tapered diameter. Starting at Φ60.5 and ending at Φ80.0, the increased capacity is ideal for high performance tuning. The TYPE-80 utilizes a flat Φ80.0 diameter flange and can be paired with the EXPREME TI TITANIUM MUFFLER TYPE-80 for optimal performance.
