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.
