Rvng SS304 Stainless Steel Dual to Single Midpipe — 4.5” Edition
For your 2020–2025 BMW G80 M3, G82 M4 & G83 M4 (S58 Engine)
INCLUDES EXTENDED BRACE
We’re proud to introduce the Rvng 4.5” Stainless Steel Single Midpipe — the largest and most aggressively engineered midpipe solution for the S58 platform. Unlike the typical 3.5” midpipes that every other company is offering, our 4.5” design delivers a massive 65% increase in flow area, unlocking performance gains you can truly feel.
This upgrade isn’t just about size — it’s about making the most of your S58’s potential. By removing the restrictive OEM midpipe and going beyond the industry-standard 3.5” setup, we’ve reduced backpressure to a minimum, resulting in faster turbo spool, sharper throttle response, and a raw, aggressive exhaust tone that sounds just as powerful as it feels.
Why 4.5” Matters:
We all know an Inch can go a long way. So while most companies settle at 3.5” and sell it as the standard — Rvng chose to offer a better product at a competitive price. When you realize you’re spending premium dollars, don’t you want the best? Our 4.5” system offers 65% more flow area, and when airflow improves, horsepower follows. Choosing Rvng means you’re not settling — you’re demanding more.
