Unlock the Full Sound and Performance Potential of Your S58
If you’re looking to unleash the true sound and performance of your G80 M3, G82/G83 M4, or G87 M2, the Rvng 4.5” Dual to Single Midpipe is the upgrade your S58 engine has been waiting for.
Why Most Midpipes Fall Short
Let’s face it — the midpipe is one of the most overlooked parts of an exhaust system. Most companies will sell you a 3.5” midpipe and call it a day. But if you're serious about performance, you'll want to take it a step further. That’s where RVNG comes in.
Our Rvng 4.5” Stainless Steel Single Midpipe isn’t just bigger — it’s smarter, louder, and more effective. With 65% more flow area compared to standard 3.5” setups, this midpipe is designed to let your S58 breathe better and respond faster.
What Makes the Rvng 4.5” Midpipe the Best?
1. More Power at the Wheels
You’re looking at gains of up to +20WHP and +32WTQ. That’s real, dyno-tested performance you can feel in the seat.
2. Turbo Spool & Throttle Response
By drastically reducing backpressure, the 4.5” design helps your turbos spool quicker and delivers noticeably sharper throttle response.
3. Aggressive Exhaust Tone
The larger pipe diameter creates a deeper, rawer exhaust note without being raspy or droney — just pure S58 aggression.
4. Quality That Lasts
Crafted from TIG-welded, mandrel-bent 304 stainless steel, this midpipe is built to last — and it comes with a lifetime warranty on fitment and craftsmanship.
5. Weight Savings
Shedding around 17 lbs compared to the OEM midpipe, this upgrade improves performance and overall vehicle balance.
Designed to Fit — and Built to Perform
The Rvng 4.5” midpipe includes an extended brace and is compatible with both OEM and aftermarket downpipes, including the BMW M Performance Exhaust (MPE). It fits all 2020–2025 G80 M3, G82/G83 M4, and G87 M2 models — both LHD and RHD — though some cutting is required for installation.
Don’t Settle for Standard — Go Bigger
At RVNG, we don’t believe in "good enough." The 4.5” midpipe is proof of that. We engineered this product because we weren’t satisfied with the status quo — and we know you aren’t either.
More sound. More power. More performance.
