These downpipes take over that section with high-flow 400 cell catalysts, lower backpressure and give the turbo more air to work with. The catalysts still meet the EPA requirements.\u003c\/p\u003e\n\u003ch3\u003eSound\u003c\/h3\u003e\n\u003cp\u003eLeave the factory exhaust behind them and the six gains mostly in depth, with the turbo easier to pick out.
