Welcome to a sound revelation for the Audi S4 B9 Platform. With such a potential powerplant, the EA839 3.0 L V6 hides a truly incredible set of vocals behind the heavy and restrictive factory exhaust equipment. With the Valvetronic Designs full exhaust system, we ensure this incredible powerplant sings all the way up to the redline. Traditionally, in the audi exhaust market, there are many different pieces of the exhaust that you have to purchase from different vendors. We have gone around this and engineered a full exhaust system that connects to the OEM downpipe or aftermarket downpipe and runs all the way back to a set of beautiful exhaust tips. The reason for this is stems from our ethos for developing exhaust systems for the audi platforms and beyond is to engineer and deliver the best sound experience with a single exhaust solution. Gone of the days where you need to combine your catback system with resonator pipes from a separate vendor. This system is your one stop solution to have unparalleled sound, and no compromises when the valves are open, the car has a very aggressive sound and tons of aggressive overrun when off throttle. With the valves closed. The car goes back to sounding like it's bone stock. There is no drone or other residence in the cabinet with the original downpipe installed.

If you are jumping into the Audi B9 platform having come from a B7 or B6 S4 with a lovely 4.2 L V8 you will short changed with the sound experience from factory, but with the Valvetronic Designs full exhaust system installed, your experience will be heightened to previous levels of enjoyment of this naturally aspirated experience. There is no displacement for displacement ultimately, but with this exhaust system, you will not feel short changed with your Audi B9 sound experience. At Valvetronic Designs we do not compromise. We recommend that you do not either when it comes to choosing the best exhaust for your B9.

Great Filter Set for Allergy‑Sensitive Families and MPG‑Minded Drivers
Size: 21-25 TLX, 18-25 Odyssey
I bought this set because I prefer handling routine maintenance myself, especially cabin and engine air filters, rather than paying dealership prices for simple jobs. The package included one cabin air filter and one engine air filter, plus a full backup set for the next service interval. Both filters installed easily and fit the 2018 Honda Odyssey exactly as expected. No trimming, no forcing, and no alignment issues. The cabin filter seated cleanly in the glove‑box housing, and the engine filter dropped into the airbox without any airflow restriction or sealing gaps. This setup is ideal for Odyssey owners who want to maintain optimal cabin air quality—especially helpful for families with allergies—and for drivers looking to keep engine airflow unrestricted for the best possible MPG and throttle response. It may not be necessary for anyone who relies exclusively on dealership service or doesn’t perform their own maintenance. Overall, this is a straightforward, high‑value filter set that installs cleanly and supports both air quality and engine efficiency for DIY‑minded Odyssey owners.

Perfect fit
Hey - pay attention to the one you pull out. All the corners are different like a puzzle piece. It takes longer to open the intake than to place the filter.

Ca10910 2017 Mitchu Outlander Sport
CA10910 Fits: Mitsubishi outlander sport 2017 Matches factory one/design etc- Only takes a few mins to swap out.The air box is frustrating to begin with, it has nothing to do with filter,don’t trim,tuck or cut. Adjust and line up the actual air box. (Not my first rodeo changing it) Idk about performance: I just changed it. Going to assume much better being my old one was overdue. Can’t beat the price/value. 5Stars bc it looks and feels identical to factory, (Will update if any issues;don’t expect any) 4/2026
