VTK Stainless Steel 4.5" Single Mid Pipe BMW G87 M2, G80 M3, G82/G83 M4

VTK Performance SS304 Stainless Steel Dual-to-Single Midpipe – 4.5" Performance Series Fits: 2020–2025 BMW G80 M3, G82 M4 & G83 M4 (S58 Engine) Includes Reinforced Center Support Brace VTK Performance is proud to offer our 4.5" Stainless Steel Dual-to-Single Midpipe for the BMW S58 platform. Designed for enthusiasts who demand maximum airflow and an aggressive exhaust note, this system features a true 4.5-inch merge section engineered to reduce exhaust restriction and enhance overall performance. Unlike conventional 3.5-inch midpipe designs, our oversized 4.5-inch configuration significantly increases exhaust volume capacity, helping your S58 breathe more efficiently under load. The result is improved throttle response, quicker turbocharger response, and a deeper, more refined exhaust tone throughout the RPM range. Why Upgrade to a 4.5" Midpipe? The factory exhaust system creates unnecessary restriction as power levels increase. By replacing the OEM dual mid-section with a larger single-flow design, exhaust gases can exit more efficiently, reducing backpressure and improving overall engine performance. Whether you're running stock downpipes or a full aftermarket exhaust setup, the VTK 4.5" Midpipe is designed to complement your build while delivering an unmistakable S58 sound. Features & Benefits Increased exhaust flow compared to traditional 3.5" designs Enhanced turbocharger response Improved throttle feel and acceleration Deeper, more aggressive exhaust tone Significant weight savings versus the factory midpipe Compatible with OEM and most aftermarket downpipes M Performance Exhaust compatible Direct bolt-on design (cutting required during installation) Construction Details Premium T304 stainless steel construction Precision TIG-welded assembly Mandrel-bent tubing for smooth airflow CNC-machined flanges for precise fitment Corrosion-resistant finish Engineered for both left-hand-drive and right-hand-drive vehicles Important Fitment Notice Due to the larger 4.5-inch diameter, vehicles with aggressive lowering setups may experience occasional contact with steep driveways, speed bumps, or road imperfections. Minor scraping will typically not affect the structural integrity or performance of the system. However, customers running extremely low ride heights should carefully consider ground clearance before purchasing.
