{"product_id":"4-0t-downpipe-set-w-200-cell-catalytic-converters","title":"4.0T Downpipe Set w\/ 200-Cell Catalytic Converters","description":"The CTS Turbo Cast Catted Downpipe Set is engineered to enhance performance for the Audi C7\/C7.5 S6, S7, and RS7 equipped with the 4.0T engine. This system replaces the OEM crossover with CAD-engineered cast stainless steel collectors and features 3\" stainless steel piping for maximum exhaust flow. It integrates high-flow 200-cell metallic catalytic converters to minimize exhaust restriction.\n\nConstructed from durable cast stainless steel and TIG welded, this downpipe set includes heat shielding to manage temperatures. The 3\" pipes utilize sleeve clamps for straightforward installation and are designed to taper to OE fitment, ensuring compatibility with factory or aftermarket cat-back exhaust systems. O2 sensor harness extensions are provided, but downpipe gaskets are not included. The manufacturer recommends purchasing new OEM gaskets (part number 4G0253115D, two required) for a seamless installation.\n\nThis product is intended for competition use only and is not street legal for use on public roads. Stage 2 software tuning is required to address the Check Engine Light (CEL); consult your software tuner for details.
