Product Details

Description

Unitronic® is proud to introduce its latest Performance Downpipe designed for 2.0TSI EA888.3 MQB vehicles, fitting 15-20 A3 Quattro, S3, and 15-19 Golf R models. This high-performance downpipe is a direct bolt-on upgrade meticulously engineered to eliminate restrictions in the stock downpipe, reducing turbo lag and enhancing the exhaust acoustics. It incorporates a state-of-the-art GESi 5-inch 400-cell per square-inch ultra-high-output catalytic converter.

The GESi GEN2 ultra-high-output (UHO+) catalytic converters were developed in collaboration with Unitronic and tailored for various Audi and Volkswagen® applications from 2017 onwards. Certified by GESi to handle power outputs of up to 1000 horsepower, this Performance Downpipe features an optimally designed cast upper section using Computational Fluid Dynamics (CFD) and robust stainless steel construction, making it the ultimate upgrade for your 2.0TSI EA888.3 vehicle.

Development:

The catalytic converter on this Performance Downpipe has been a key development focus for Unitronic Engineers. Through extensive collaboration with GESi and the iterative refinement of their G-Sport Emissions Systems Catalytic Converters over the years, their goal was to ensure that the product would meet compliance demands and align with Unitronic's performance objectives.

Drawing on the outstanding performance of these catalytic converters in other areas of Unitronic's product lineup, the engineering team once again opted for a GESi 5" UHO+ converter. This choice was driven by its ability to meet the requirements of the 1.8/2.0TSI EA888.3 engines and its remarkable 1000-horsepower rating. Paired with CFD-optimized castings in the upper downpipe section, the substantial 5-inch catalytic converter promotes exceptional exhaust flow.
