XForce 4" to 3" Turbo Downpipe & High-Flow Cat Kit - Audi RS3 8V & TT RS FV - ESRS317KITB

Unlock the full potential of your 2.5L TFSI engine with the XForce Turbo Downpipe kit for the Audi RS3 (8V) and TT RS (FV). This premium upgrade is designed to maximize exhaust flow by replacing the highly restrictive factory component. Crafted from high-quality 304 stainless steel, the system features a massive 4" inlet that transitions smoothly into 3" mandrel-bent tubing. By deleting the secondary catalytic converters and utilizing a 200-cell high-flow metallic race cat, this kit significantly reduces backpressure, resulting in improved throttle response, increased horsepower, and a much more aggressive, visceral exhaust note.
