Exhaust mods are great until that P0420 code pops up. Fixed mine with a 90° spacer that actually has a mini-cat built-in. Huge difference in keeping the sensor happy without a full tune. #minicatalytic #carprojects #diyautorepair

Tired of that stubborn P0420 code after an exhaust upgrade? Found a clean, stainless 45-degree fix with a built-in mini cat that actually works without needing a welder. Simple, effective, and keeps the dash clear. #minicatalytic #carprojects #diyautorepair
