ARK exhaust was installed today. I've put around 200 miles on it already. A combination of twisties, country two lane, city stop and go, lastly interstate at 80/85 mph. Gotta love TX ? Noticeable difference in sound quality. Not fart can ! Very mellow. Unnoticeable at highway speeds. No cabin drone. Both Corsa and Borla could learn from ARK. Excellent build quality. Techs at Alamo were very impressed. They work on a lot of metrics and have seen some real garbage come through the shop. Think back alley eBay type.
