Untd. Performance Catted W/Shield Downpipe – Audi SQ5 B9 3.0T 17-18

Description

Unlock the true performance potential of your Audi SQ5 B9 3.0T with the Untd. Performance Catted Downpipe w/ Integrated Heat Shield. Engineered to balance power gains and sound refinement with improved heat control, this high-flow downpipe replaces the restrictive factory unit while retaining a performance catalytic converter—making it ideal for enthusiasts who demand power without compromise.

Key Features:

High-Flow Sport 200 Cell Catalytic Converter
This downpipe features a premium high-flow catalytic converter that significantly reduces backpressure compared to the OEM unit, while still helping to control emissions and limit odor. The result: increased power, smoother boost delivery, and enhanced drivability—perfect for street or lightly tuned setups.

Integrated Heat Shielding
To manage under-hood temperatures, the downpipe includes a built-in heat shield that protects nearby components from thermal stress. Whether you’re pushing hard on a canyon road or sitting in traffic, this feature maintains performance consistency and safeguards engine bay integrity.

Sharper Throttle Response & Turbo Efficiency
The improved flow characteristics reduce turbo lag and allow for faster spool-up, resulting in a more responsive throttle and immediate power delivery. Gains are especially noticeable in the mid-range, where the 3.0T V6 comes alive.

Aggressive, Yet Refined Exhaust Tone
This catted setup unlocks a deeper, more assertive exhaust note while avoiding the excessive volume or harshness of a full catless system. Turbo spool, pops, and crackles become more pronounced—delivering a sound experience worthy of Audi’s performance pedigree.

Precision Construction
Fabricated from TIG-welded 304 stainless steel and finished with CNC-machined flanges for an exact OEM fit, this downpipe is built to handle the heat and pressure of high-performance driving, all while ensuring long-term durability.

Compatibility:

• Audi SQ5 B9 (2017–2018)

• Engine: 3.0L TFSI V6 (Single Turbocharged)

The Untd. Performance Catted Downpipe w/ Heat Shield is the ultimate upgrade for your SQ5—combining improved flow, thermal control, and a refined exhaust tone into one track-ready, street-friendly package.
