AWE Tuning GR Corolla Exhaust - Diamond Black Tips

T304L Stainless Steel

Touring Edition:

• The epitome of hot-hatch tone. At the intersection of sophistication and aggression lies the Touring Edition Exhaust – a 3” T304L stainless steel downpipe-back configuration providing a deep, full-bodied, powerful soundtrack that gives the GRC a complete attitude change from idle to full-throttle (and everything in between). 
  
  
• Featuring AWE’s patented drone-killing 180 Technology®, the Touring Edition unlocks every bit of raw nature out of the 1.6L, minus the very particular frequencies that cause discomfort in the cabin (read: these particular frequencies were capable of truly breaking the threshold of the GRCs cabin structure to cause what most would perceive as drone at highways speeds). 
  
  
• 180 Technology® resonators feature zero packing material to prevent tone change over time, while also featuring a straight-through design for optimal flow. Their sole purpose is to destroy drone-prone frequencies while providing an uncongested exhaust note paired with straight-pipe performance.
  

Track Edition:

• For those who like their volume like their speed (and want to feel the raw nature of the GRC’s potent 3-cylinder at all speeds) the Track Edition features a non-resonated mid-section (i.e. no 180 Technology®). It’s even louder (in & out), it’s cost-effective, and isn’t for the faint of heart–you’ve been warned.

During R&D, AWE conducted a (quite painstaking) full evaluation of the factory valve and its behavior under various driving conditions to determine its reason for existing. The valve is not controllable by the driver whatsoever–meaning regardless of the driving mode, buttons, settings, etc, there’s no opening/closing the valve from within the cabin. It works directly off of throttle input and only opens upon a certain breach of a threshold declared by the ECU very low in the rev range. Its sole purpose is for backpressure, and considering the factory exhaust design, flow is given priority to the center outlet (the larger one). The factory rear muffler is baffled with no packing material, and only directs flow to the left and right exits when cruising at part throttle or light throttle inputs.

After confirming this, and given our configurations already remove any backpressure issues organically, it would have been pointless to incorporate a valve.
