There are a number of options:
The SwitchPath™ Exhaust: SwitchPath™ Technology keeps the S3 quiet and comfortable while cruising, but give it the boot and you’ll unlock an aggressive and exotic exhaust note.
The Track Edition Exhaust: The lower priced sibling, the Track Edition Exhaust is crafted of the same quality T304 stainless steel, made in house, and delivers the same power gains as the SwitchPath Exhaust, but skips the valves and keeps the volume up in the mid-range.
Performance Downpipes: Both res and non-res versions feature our No Check Engine Light Guarantee, Fitment Guarantee, a unique flex-pipe section to isolate engine movement, and both use a EURO 6 compliant 200 cell high flow HJS catalyst. There is a Lifetime Warranty on the downpipes (one year on the catalysts).
Packages: Both the SwitchPath™ Exhaust and the Track Edition Exhaust are available with downpipes as a package for savings.
