Our 991TTs development car arrived today and in the next few weeks, we will be generating our solution for the 991TT/TTs exhaust. It is currently poised in our product development, awaiting the design phase, where we will analyze the OEM exhaust and design our solution for increased performance, improved sound and weight savings over the original factory system. The fabrication and testing phase of a new model system is our favorite aspect of the Porsche performance exhaust business - it's exciting and extremely enjoyable to witness a new exhaust transform from an idea on paper to real road and track testing! Stay tuned for pictures of the final product and private test track video in the next few weeks.
