The factory Supra exhaust is built for quiet cruising. Injen's cat-back swaps everything behind the catalytic converters for larger mandrel-bent stainless tubing and straight-through mufflers, while keeping the valve so you still get a quiet mode and a loud mode. This version finishes with carbon fiber tips.
What you get
- Stepped 304 stainless tubing, 3.5 in through the front and middle sections, stepping down to 3.0 in at the rear. It is mandrel bent and TIG welded by hand.
- Two oval straight-through mufflers with a polished finish, fed by a cast Y-pipe that splits flow evenly.
- Working exhaust valve for a quieter normal mode and a louder sport mode.
- Dual 4.5 in carbon fiber tips.
- V-band connections that use the factory mounting points and factory-style hangers, with the hardware included.
Good to know
- Injen's dyno figures show 11 hp and 9 lb-ft at the wheels.
- The valve needs your factory exhaust valve motor, which is not included.
- Injen suggests a professional install, since a lift or special tools may be needed.
