Performance Downpipes for Audi S8 D4 4.0t TSFI

The DTM-Tuning Performance Downpipes are engineered specifically for the Audi S8 D4 Quattro 4.0TFSI models from 2013 to 2019. These downpipes incorporate an OEM X-crossing design and utilize OEM-spec bottom flanges, ensuring a straightforward installation and integration with your existing exhaust system. Constructed from the highest quality 2mm wall T304L stainless steel, these downpipes are built for durability and performance. The flow-optimized, smooth transition design contributes to increased exhaust flow, which can help increase the lifespan of your turbos and reduce under-hood temperatures. Additionally, they are crafted to add a pleasant tone to your exhaust note and are compliant for both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles. This kit comes with OE-style Heat Shielding featuring a ceramic inner liner, a DTM-Tuning thermal management feature designed to reduce radiant heat by up to 70-80%. Also included are Straight Tunable 02 Spacers with three inserts to help prevent Check Engine Light conditions when used with a competition model without proper tuning. Optional configurations are available, including GESI GEN2 400cpsi catalytic converters rated for 1000hp, which offer a balance of performance and emissions control, or HJS HD 200cpsi Ultra High-Performance Catalytic Converters manufactured in Germany. You can also opt for a version without catalytic converters. The product is backed by a limited lifetime warranty.
