  • Fabspeed's Sport Catalytic Converters for the Porsche 991.2 GT2RS are high-flowing, direct bolt-on replacements for the bulky & restrictive factory catalytic converters and OEM titanium muffler.
  • Very aggressive "straight-pipe" system which replaces/bypasses the factory muffler with no CEL guaranteed! (Pictured with our complementary turn down tips)
  • While the hardware made significant gains alone, we found its full power potential was realized when combined with our proprietary ECU tune, of course. As tested on our 2019 GT2 RS, our Competition Sport Cat Race Pipes with ECU Tune adds an insane 99 whp at 6200 RPM and 125 ft/lbs of torque at 3200 RPM. Blast off!
  • XXL HJS German imported 200 cell HD European level 6 wash coat catalytic converters. We utilized the largest HJS HD German cores that will physically fit on the 991.2 GT2 RS. Unprecedented flow without a check engine light, guaranteed!
  • Though maximum gains are seen while combining with an ECU Tune, we designed our Compeition Sport Cat RAce Pipes to increase power with our without a software upgrade.
