Revolutionize your driving experience with the E46 M3 Valved Performance Catback Exhaust from Turner. Crafted for the discerning driver, this lightweight and free-flowing exhaust boast two independent valved mufflers, offering two distinct driving experiences. Shedding 19lbs or more from the factory exhaust, the Turner catback delivers refined daily driving with closed valves, providing a smooth exhaust note. When the valves open, unleash an untamed racecar roar, experiencing heightened performance and a pure S54 sound. The flexibility to switch between the two at the touch of a button offers the best of both worlds.
Amplify airflow and let your S54 breathe with the Turner Open Intake System. With a 200% greater flow than the factory airbox, this intake enhances induction noises, providing an exhilarating auditory experience. The design integrates seamlessly with OE fresh air scoops, maintaining stock mounting locations and incorporating a 4" conical filter for maximum flow and filtration efficiency.
Introducing the do88 Intake System for BMW 320i and 330i G20 – Engineered for Maximum Performance!
At do88, we understand that filtration, airflow, and heat management are crucial when designing an intake system for turbocharged engines.
Our intake system is designed to provide the turbo with excellent filtration, an optimized airflow path, and consistently low inlet temperatures. One of the key challenges with the B48/B46 engine is the intake system’s location near the exhaust manifold, which generates intense heat and causes rapid heat soak.
High intake air temperatures (IATs) can significantly reduce engine performance, as hot, less dense air makes it harder for the turbo to build boost efficiently. To address this, our fully sealed intake system minimizes heat exposure and maintains low IATs. However, fully sealed systems can face airflow restrictions due to the factory airbox’s single air feed. We resolved this by adding a secondary air feed and incorporating a heat shield into the airbox design to block heat from the exhaust manifold. The large 7” airbox ensures ample airflow around the filter and accommodates strut braces.
We replaced the stock intake hose with a high-flow 102mm (4”) mandrel-bent aluminum pipe paired with a custom silicone hose. The system also features a custom-designed air filter with tightly woven cotton gauze for exceptional filtration. The filter is washable, reusable, and built for long-lasting performance.
Unlike the stock air filter box and intake hose, which are designed with silencers to reduce turbo and induction noise, the do88 system eliminates these elements. This allows for a more pronounced and engaging turbo spool and induction sound, giving you a truly dynamic driving experience.
