⚠ Lead Time & Order Terms
Required Reading
Fi EXHAUST components are bespoke production items — manufactured on demand specifically for your order. Materials are allocated and manufacturing begins as soon as your order is placed. The order cannot be cancelled, refunded, or returned for any reason including change of mind, longer-than-expected lead time, fitment compatibility (verify before ordering), shipping delays, or any other reason. By purchasing this product, you acknowledge and agree to these terms and to FFP’s full Terms & Conditions.
Before You Order
Why is the lead time so long?
Fi EXHAUST is not a stocked product line. Every catback, downpipe, and header pair is hand-built at Fi’s Taiwan facility when ordered — T304 stainless mandrel-bent, TIG welded, valvetronic actuators fitted, tip finish applied, then bench-tested before shipping. The 4–8 week window covers production + air freight from Taiwan to FFP’s Thousand Oaks shop, then to you.
Why no refunds or cancellations?
Because Fi allocates raw materials and starts production within hours of order receipt. Materials are cut, bent, and welded to your exact spec (tip color, configuration). There is no resale market for a half-built bespoke exhaust. This is the same model every premium exhaust maker (Akrapovič, iPE, Capristo, ARMYTRIX) uses for made-to-order systems. We’re straight with you about it up front.
How do I know it will fit my car?
Message us BEFORE you order. Send VIN, trim package, and any modifications (downpipe, headers, sport cats, OPF delete). We verify against Fi’s fitment database and confirm before you commit. Once the order is placed, fitment confirmation is your responsibility — we cannot accept returns for fitment issues that pre-order verification would have caught.
Will this trigger a CEL (Check Engine Light)?
Depends on the product. Valvetronic muffler catbacks generally retain factory cats/OPF and do not trigger a CEL. Catless downpipes / headers / Race Version full systems remove emissions hardware and will trigger a CEL unless paired with a tune or O2 simulator. Each product page calls out CEL risk in the fitment section — read carefully or ask us.
Do I need to tune my car?
Catback-only installs (this product type) do not require a tune — valves run off the factory exhaust control signal. Catless / Race Version installs typically require tuning or a CEL fix. We coordinate tuning through our trusted partners (Cobb, EMS, MHD, etc.) if needed.
What if there’s a manufacturing defect?
Fi EXHAUST covers manufacturing defects under their published warranty. FFP coordinates the claim directly with Fi on your behalf — you don’t deal with Taiwan customs or factory back-and-forth. Defects are rare; Fi has built valvetronic systems since 2013 and the QC is industry-leading.
Can I get faster shipping?
The 4–8 week window is dominated by production time, not shipping. Air freight is included. There is no “rush production” option from Fi.
Audi MK3 (8S) TT 2.0T Quattro Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.
The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase from 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.
When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.
Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode, or optional Fi EXHAUST remote control and mobile App.
The unique sound and performance for Audi MK3 (8S) TT 2.0T Quattro is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
Please note each part of the Fi EXHAUST system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.
Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.
