Do I need an ECU tune after installing these downpipes?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Installing catless or high-flow catted downpipes will significantly alter the exhaust flow and trigger a Check Engine Light (CEL). A Stage 2 ECU tune is highly recommended to clear the CEL and fully optimize the engine for the increased airflow, yielding maximum horsepower gains.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e3. What is the difference between Catless and High-Flow Catted options?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe Catless version provides maximum exhaust flow, the loudest V8 sound, and the highest power gains (ideal for track use). The High-Flow Catted versions (100\/200\/300 cell) use performance catalyst cores to reduce exhaust fumes and tone down the raspiness, making them better suited for street driving while still offering a massive upgrade over stock.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e4.
