Buying an aftermarket exhaust for your Honda or Acura is a significant investment. Here's how to make the right choice. Function Werk has been engineering exhaust systems for Honda and Acura platforms since 2019. This guide covers everything you need to know before purchasing — from fitment verification to material selection to installation. Step 1: Verify Fitment First The most important factor in any exhaust purchase is fitment. A universal system may fit with modification, but a platform-specific system will bolt directly to your factory mounting points without cutting, welding, or adapters. Function Werk builds every exhaust for a specific vehicle and engine combination. Our product titles include the exact year range, model, engine displacement, and trim level. If your vehicle is listed, the system will fit. Step 2: Choose Your Material 304 Stainless Steel — The best choice for most owners. Excellent corrosion resistance, great sound, accessible price. This is what the majority of Function Werk customers choose. Titanium — For owners who want the lightest, most exotic option. Significantly lighter than stainless, with a distinctive higher-pitched sound and natural heat coloring on the tips. Available for select platforms. Step 3: Decide on Scope A complete exhaust upgrade typically involves three components: Sport Exhaust (Cat-Back): Replaces everything from the catalytic converter back. The most impactful upgrade for sound and appearance. Front Pipe / A-Pipe: Replaces the section between the turbo/engine and the cat. Improves flow and throttle response. Performance Pipe: Replaces the factory charge pipe (turbo models). Improves turbo response and airflow. You can purchase any component individually or combine them for a complete system. Step 4: Consider the Full Brake Upgrade While you're upgrading your exhaust, consider completing the performance package with Function Werk brake components — stainless steel brake lines, 2-piece rotors, and high-performance brake pads are available for most platforms.

The Acura MDX is the best-selling three-row luxury SUV in history. It deserves a better exhaust than the factory unit. Function Werk builds exhaust systems for multiple MDX generations — from the 2017–2020 A-Spec to the 2022+ Type S. Every system is engineered for the specific MDX platform, not adapted from a universal kit.

Shop MDX Type S Brake Lines → Frequently Asked Questions Will the MDX exhaust change the interior sound? Function Werk MDX exhaust systems are tuned to enhance the exterior exhaust note without significantly increasing interior cabin noise. The MDX remains comfortable for family use. Is the exhaust compatible with the MDX's active noise cancellation system? Yes. The exhaust system does not interfere with the MDX's active noise cancellation (ANC) system. Does the exhaust fit the MDX with the factory trailer hitch? Fitment is verified for the standard MDX configuration. If your vehicle has a factory trailer hitch, please contact us before ordering to confirm clearance.

Two materials. Very different outcomes. Here's how to choose the right exhaust for your build. Function Werk offers exhaust systems in both 304 stainless steel and aerospace-grade titanium for select Honda and Acura platforms. The right choice depends on your priorities — budget, weight, sound, and long-term goals. 304 Stainless Steel Exhaust Stainless steel is the industry standard for aftermarket exhaust systems. Function Werk uses 304-grade stainless — the same alloy used in marine and food-grade applications — for maximum corrosion resistance. Durability: Excellent resistance to rust and corrosion in all climates Sound: Deep, full exhaust note with good volume at full throttle Weight: Heavier than titanium — typically 15–25% more weight Cost: More accessible price point Best for: Daily drivers, street builds, owners who want the best value Titanium Exhaust Titanium is the choice for owners who want the absolute best. Function Werk titanium systems are built from aerospace-grade titanium — the same material used in high-performance motorsport applications. Weight: Significantly lighter than stainless — meaningful reduction in unsprung mass Sound: Higher-pitched, more exotic exhaust note with distinctive titanium character Heat resistance: Superior thermal properties — titanium handles extreme heat better than stainless Aesthetics: Distinctive blue/gold heat coloring on tips that develops naturally over time Cost: Premium price — titanium is more expensive to source and fabricate Best for: Track builds, weight-conscious owners, enthusiasts who want the best Which Should You Choose? For most street-driven Honda and Acura owners, the 304 stainless system delivers 95% of the performance at a more accessible price. If you track your car, want the lightest possible system, or simply want the most premium option available, titanium is worth the investment. Available Titanium Systems from Function Werk Titanium Sport Exhaust — 2021–2025 Acura TLX V6 (3.0T) Type S Titanium Sport Exhaust — 1991–2005 Acura NSX V6 (3.0L/3.2L) Frequently Asked Questions Will titanium rust or corrode? No. Titanium is naturally corrosion-resistant and will not rust. The blue/gold discoloration that develops on titanium tips is a heat-induced oxidation effect — it is cosmetic and does not affect performance or durability. Is titanium louder than stainless? Titanium typically produces a slightly higher-pitched, more exotic sound compared to stainless. The difference is noticeable but not dramatic — both materials deliver a significant improvement over the factory exhaust. How much lighter is titanium? Titanium exhaust systems are typically 30–40% lighter than equivalent stainless steel systems. For a full cat-back system, this translates to a meaningful reduction in unsprung weight.

The 2021–2025 Acura TLX Type S comes with Brembo brakes from the factory. Function Werk takes them further. Whether you're upgrading for track days, canyon runs, or simply want better pedal feel and fade resistance, Function Werk has a complete brake upgrade path for the TLX Type S platform. 2-Piece Brake Rotors for 2021–2025 Acura TLX Type S The Function Werk 2-Piece Brake Rotors for the 2021–2025 Acura TLX V6 (3.0T) Type S are engineered for improved heat dissipation and reduced unsprung weight compared to the factory solid rotors. The two-piece design allows the rotor hat and disc to expand independently, reducing thermal stress and warping. Fitment: 2021–2025 Acura TLX V6 3.0T Type S Improved heat dissipation over OEM Reduced unsprung weight Compatible with factory Brembo calipers Shop TLX Type S Brake Rotors → Stainless Steel Brake Lines for 2021–2025 Acura TLX Type S The Function Werk Stainless Steel Brake Line Kit for the 2021–2025 Acura TLX V6 (3.0T) Type S replaces the factory rubber brake lines with braided stainless steel.

Shop TLX Type S Brake Pads → Frequently Asked Questions Do I need to upgrade all brake components at once? No. Each component can be upgraded independently. However, for track use, we recommend upgrading rotors, pads, and lines together for the best performance and safety margin. Are the 2-piece rotors street legal? Yes. Function Werk 2-piece rotors are designed for both street and track use. They meet all requirements for street-legal operation. How long do the brake pads last? Pad life depends on driving style and usage. For primarily street driving, expect comparable or better longevity than OEM pads. Track use will reduce pad life significantly — plan for more frequent inspection. Will these brake lines affect my ABS or stability control? No. Stainless steel brake lines are a direct replacement for the factory rubber lines. They do not affect ABS, stability control, or any other electronic brake systems.

Start with fitment: 2021–2025 Acura TLX Type S 3.0T Comparing exhaust options for your TLX Type S? Function Werk lists both a 304 stainless-steel Sport Exhaust and a Titanium Sport Exhaust for the 2021–2025 Acura TLX V6 3.0T Type S, UB7, SH-AWD. Match that application to your vehicle before comparing materials, finishes or available configurations. Both product listings specify OEM valve-control retention, a 3-inch collector, dual 2.5-inch piping, dual mufflers and quad 4-inch exhaust tips. The differences below come from the current product specifications—not an assumed sound or horsepower result. Option 1: Sport Exhaust System (304 Stainless Steel) The stainless-steel Sport Exhaust is the option to compare if you want the listed polished finish and the current tip/valve configurations. Material and finish: 304 stainless steel; polished finish specified in the product description. Layout: 3-inch collector, dual 2.5-inch piping with a stated 2.35-inch inner diameter, non-resonated design and dual mufflers. Tips and valves: quad angle-cut, offset 4-inch tips; OEM valve-control functionality retained. Installation: the listing describes a complete bolt-on kit with installation hardware included and no modification required for the stated application. Check TLX Type S Sport Exhaust configurations, price and availability. Option 2: Titanium Sport Exhaust The titanium system uses a different material and finish while retaining the same listed Type S application and factory valve-control functionality. Material and finish: pure titanium; brushed finish specified in the listing. Layout: 3-inch collector, dual 2.5-inch piping with a stated 2.35-inch inner diameter, non-resonated design and dual mufflers. Tips and valves: quad angle-cut, offset 4-inch tips; OEM valve-control functionality retained. Published system weight: 46 lb. The stainless listing does not provide a comparable system weight, so this guide does not claim a measured weight saving between the two. Installation and images: the listing describes a complete bolt-on kit with hardware included. It identifies the photos as reference images; confirm current finish details before ordering. Check TLX Type S Titanium Exhaust specifications, price and availability. Which Should You Choose? Start with the correct fitment, then compare the listed material, finish, current price and orderable configuration. Use the product pages for live availability rather than assuming every tip option is in stock. If weight is a deciding factor, request comparable system weights before treating material alone as a measured saving. For sound, look for a recording of the exact exhaust on a matching TLX Type S. Check other modifications, valve configuration, microphone position and whether the recording is exterior or in-cabin. Both listings describe non-resonated systems; this guide does not promise a particular cabin sound, drone-free cruising or an unmeasured power gain. Frequently Asked Questions Does this exhaust fit a TLX 2.0T or A-Spec? These two listings specify the 3.0T Type S application. Do not assume that fitment transfers to another engine or trim. Verify your year, engine, drivetrain and any existing modifications against the individual product listing. Do the systems retain factory valve control? Both product descriptions state that OEM valve-control functionality is retained. Check the selected configuration and installation requirements on the relevant product page. Is installation hardware included? Both listings describe complete bolt-on kits with installation hardware included. Have an installer check your specific vehicle and any added equipment before booking the work. Will an aftermarket exhaust affect my warranty? Read the disclaimer and warranty terms in the product page's Product Info section. Ask your vehicle warranty provider how the proposed modification could affect a specific claim; this guide does not replace those terms. How do I check shipping timing? Check the selected product's current availability and the shipping information. If you need the system for a particular installation date, contact Function Werk before ordering rather than relying on a general delivery estimate. Explore the full TLX Type S collection or read the TLX Type S brake upgrade guide for the next part of your build.
