  • HJS HD 200cpsi Ultra High-Performance Catalytic Converters. Made in Germany to European standards by the most reputed motorsport and tuning converters manufacturer - HJS Emission Technology GmbH & Co. KG. In most applications we use HD-Design series matrixes with triple foil winding and Euro 5/6 coating. They allow you to achieve flow numbers close to straight pipes while meeting strict emissions standards. Combined with exteremaly robust matrix HJS cats can forgive you some tuning mistakes or track-day abuse. Please don't be confused when shopping for the HJS catted downpipes as there are lower grade Euro 1-3 cheap converters might be used and they are not suitable for the modern vehicles. >>
  • G-Sport GEN2 400cpsi Catalytic Converters. New 2020 converters line with S-wound metall core for improved strength & performance and proprietary coating to meet latest emissions regulations. EPA Compliant for vehicles 2017 and newer and allow you to pass emissions tests*. 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.
  • G-Sport GEN1 300cpsi UHO Catalytic Converters. The main high flow converters line from GESI, well known for years for their durability, high flow 300cpsi core and consistent emissions reduction. EPA Compliant for use on OBD1/OBD2 Vehicles up to 2016 model years. Rated by the manufacturer up to 850HP per converter, eliminate gas smell and even allow you to pass emissions tests* and avoid error codes in some applicatios. In 2022 GEN1 converters getting major update to S-wound core similar GEN2 series. More strength and withstanding up to 1,700F/ 925C expected (vs 850C for the current design).
  • HJS Motorsport 100cell Catalytic Converters available on request. Message us for more info and custom orders.
  • 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 racing cars engineers who used it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR product. Usual thermal wraps or ceramic coatings not even close in effectiveness and durability to the Heat Shielding. Please be aware of fake shielding when nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it just doesn't work as expected.

  • Significant power gain
  • Faster spool up and better throttle response
  • Increasing the life of the turbos 
  • Reducing underhood temperature
  • Adds a very nice tone to the exhaust
  • 100% bolt-on installation
