Free up the V12 in your Lamborghini Revuelto with Fabspeed’s high‑flow German HJS Sport Race Cat: engineered to replace the restrictive factory catalytic converters with racing-grade trimetallic cats that flow roughly 90–93% of a straight pipe. Constructed with premium T304 stainless steel and thermally insulated for heat control, this bolt‑on upgrade slashes exhaust restrictions, drops weight, and transforms exhaust tone — delivering a race‑bred, high‑pitched V12 soundtrack with exotic character.
Designed specifically for all Lamborghini Revuelto models — Coupes & Spiders, worldwide, model years 2024 and newer.
Direct‑bolt replacement for the stock catalytic converter section — engineered with CAD‑scanned fitment to mate with factory exhaust layout and hardware.
Compatible with both stock exhaust or aftermarket exhaust systems — ideal for either a “catted high‑flow” build or part of a full performance exhaust.
Full set of high‑flow sport catalytic converter housings fitted with German‑imported 200‑cell racing catalytic cores (from HJS Emitec).
Mandrel‑bent T304 stainless steel tubing (76 mm / 3.0" diameter), CNC‑machined flanges, and all necessary hardware for bolt‑on installation.
Heat‑shield / thermal wrapping (2000 °F–rated, stainless wrap) to contain exhaust heat and protect surrounding components.
Catalytic converter cores: German HJS Emitec trimetallic racing‑grade cats (200‑cell HD/200 CPSI) — high‑flow, high‑temp capable, and designed to maintain catalytic function while minimizing restriction.
Tubing: 76 mm (3.0″) mandrel‑bent T304 stainless steel throughout.
Flow rate: approximately 90–93% of a straight‑pipe flow (versus stock cats), giving near‑race performance with catalytic presence.
Weight savings: roughly ‑24 lbs (–10.5 kg) compared to the factory valved muffler / cat back + stock cats.
Fitment: 2024+ Lamborghini Revuelto (all factory exhaust layout versions).
High‑flow German HD catalytic cores: HJS trimetallic sport cats deliver near-straight‑pipe flow while retaining catalytic function — balancing performance and emissions compliance.
Significant exhaust flow improvement & weight reduction: With larger-diameter tubing, freer flow, and lighter construction, the system reduces exhaust back‑pressure and rear‑end mass, improving throttle response and exhaust scavenging.
Aggressive, race‑car V12 sound: When paired with a performance exhaust (e.g. Fabspeed’s long‑pipe X‑pipe), expect a high‑pitched, exotic V12 soundtrack — deep and aggressive on throttle, sharp and visceral under load — reminiscent of motorsport intensity.
Thermal management built‑in: Heat‑shielding and thermal wrapping help manage exhaust temperatures, protect surrounding components, and maintain catalyst efficiency under high heat.
OEM‑style bolt‑on installation: Because the system is CAD‑designed and built to OEM exhaust layout, it bolts directly onto factory mounting points — no custom fabrication or permanent modification needed.
