Hand-fabricated from T304 stainless steel with high-flow 300-cell metallic substrate GREEN cats, these downpipes bolt directly to the factory turbochargers and OEM exhaust without cutting or welding while maintaining 49-state emissions compliance.\u003c\/p\u003e\n\u003cp\u003eThe mandrel-bent tubing, 3\/8-inch laser-cut flanges, and full TIG welds ensure zero leaks under boost pressures exceeding 25 PSI and support power levels over 800 HP with larger turbos or E85 tuning.
