Description
Upgrade the sound and performance of your Porsche Boxster S or Cayman S 987 / 987.1 3.4L with the STRATEC Valved T304 Stainless Catback Exhaust System, engineered to enhance exhaust flow while retaining driver‑controlled sound flexibility.
Constructed from premium SS304 stainless steel, this system reduces factory backpressure to improve throttle response and mid‑range power while delivering a sharper, more aggressive flat‑six exhaust note. The integrated valve system allows you to switch between refined cruising and full race sound on demand.
