Sound Perfection: AWE 180 Technology®

Perfect tone, compliments of AWE 180 Technology®.

As exhaust gases exit the 3.0T engine and flow into an AWE 180 Technology® 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.

Exhaust configurations recommended for use with aftermarket catalysts:

Given the increase of airflow when introducing an aftermarket catalyst, special resonators were developed to keep sound frequencies in check. These larger resonators are included in exhaust configurations labeled as "Resonated for Performance Catalyst," and available independently (to be added to existing AWE exhausts) via the "Resonator Conversion Kit."

Please note: exhausts labeled "Resonated for Performance Catalyst " and the Resonator Conversion Kit are recommended to be used with an aftermarket catalyst.

Track Edition Exhaust

For those who like it loud, go Track.

The Track Edition Exhaust is equipped with the same precision-engineering as its Touring Edition counterpart, minus the resonators up front and 180 Technology® resonators in the rear. Instead, the Track Edition comes complete with non-resonated downpipes and straight pipe sections -- leaving the integrated x-pipe as the only filter.

This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself.

Tip :

All tip options include the AWE logo, and double walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste.
