Audi A1 1.4 TFSI Custom Exhaust & Remap Upgrade
Performance Exhaust Enhancement
This Audi A1 1.4 TFSI arrived for a full DKU Performance stainless steel cat-back system, engineered to deliver improved flow and a sportier tone. Although the closest high-volume term is **Audi A3 Exhaust**, the same performance principles apply, making this upgrade ideal for drivers seeking sharper throttle response and a more engaging drive.
ECU Remap Power Gains
Once the custom exhaust system was installed, we applied a DKU Performance ECU remap. The Audi A1 1.4 TFSI increased power from 120bhp to an estimated 145bhp, with torque rising from 148 ft-lbs to around 195 ft-lbs. This combination of exhaust and remap transforms everyday drivability and mid‑range pull.
High‑Grade Stainless Steel Construction
At DKU Performance, we manufacture everything in-house using premium 304/316 stainless steel. From performance back boxes to cat-back exhausts and full turbo‑back systems, every setup is designed for maximum durability, tone and performance.
