Available Options:

  • GESI GEN2 400cpsi- catalytic converters rated for 1000hp. The new GEN2 series provides a significant improvement in exhaust flow over stock and offers the latest emissions technology. EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California). Ideal for forced induction and capable of withstanding up to 1,700F/ 925C core temp. At REDSTAR we rank them as the ones with the best performance/pollution reduction balance. >> Read more about G-Sport by GESI cats.
  • HJS HD 200cpsi- Ultra High-Performance catalytic converters. Made in Germany. These extremely robust converters allow you to achieve flow numbers close to straight pipes while meeting strict Euro 6 emissions standards. >> Read more about HJS cats.
  • OE-style Heat Shielding with ceramic inner liner - signature REDSTAR thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.
  • Optional Gasket set- 2 upper, 2 lower (Recommended if car has over 50K miles)
  • Tunable Straight 02 Spacer pair - simple inexpensive way to trick the ECU and deal with error codes. Not a 100% solution and we always recommend the ECU tune as the only proper way to do it, but that works and is quite popular for some platforms.
