High exhaust gas temperatures and direct-injection combustion byproducts steadily foul the substrate, causing persistent P0420\/P0430 diagnostic trouble codes. Furthermore, age and road vibration induce stress cracks along OEM pipe welds and flange faces, introducing pre-catalyst and post-catalyst oxygen infiltration that disrupts closed-loop fuel trim feedback and causes low-RPM hesitation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on dual-side replacement assembly, this converter set utilizes high-grade stainless steel casing for corrosion resistance and thermal endurance. Inside, dense ceramic honeycomb substrates feature an optimized cell structure that promotes rapid light-off while minimizing backpressure downstream of the exhaust manifolds. Precision-machined mounting flanges match OEM mid-pipe geometry, ensuring gas-tight sealing and proper oxygen sensor engagement without custom cutting, bending, or welding.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2006-2015 Lexus IS\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4GR-FSE 2.5L V6 \/ XE20, XE30 (GSE20, GSE25, GSE30)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e204 hp \/ 185 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2013 Lexus IS250 Base \/ F Sport 2.5L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2014-2015 Lexus IS250 Base \/ F Sport 2.5L V6 (RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2010-2015 Lexus IS250C Convertible 2.5L V6 (RWD)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus Precision Calibration\u003c\/h3\u003e\n\u003cp\u003eBuilt to maintain factory emissions control architecture, this converter assembly preserves factory acoustics while delivering unobstructed exhaust flow and precise stoichiometry management across the entire 4GR-FSE powerband.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489478709496,"sku":"DS-E2L9993QH","price":188.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-lexus-is-2006-2015-2-5l-1.jpg?v=1789163347","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-lexus-is-2006-2015-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
