Sound Perfection: AWE Tuning 180 Technology™

As exhaust gases exit the Jetta 1.8T's engine and flow into an equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

Performance Downpipe

To further hone the tone and performance of your Jetta 1.8T, we're offering the AWE Tuning Performance Downpipe. Featuring a unique flex-pipe section to isolate engine movement, AWE Tuning's No Check Engine Light Guarantee, Fitment Guarantee, and our Lifetime Warranty on the downpipe (one year on the catalyst).

This downpipe does not fit the 2014 pre-facelift vehicle.

Please note the AWE Tuning 1.8T/2.0T Jetta Performance Downpipe is for offroad use only.
