Description

RVNG Stainless Steel Dual to Single 4” Midpipe

We are proud to introduce our RVNG 4″ Stainless Steel Single Midpipe for the S55-powered F80/F82/F83 M3 & M4 — the largest midpipe available on the market for these models. This upgrade is one of the most cost-effective modifications you can make to your S55, with potential gains of 18+ whp and 30+ wtq when tuned.

By replacing the highly restrictive OEM midpipe, back pressure is dramatically reduced, resulting in faster turbo spool, improved exhaust flow, and a noticeably more aggressive exhaust note.

Designed to fit perfectly on both the F80 M3 and F82/F83 M4, our midpipe delivers an instant performance difference the moment it’s installed. You’ll also benefit from a 17 lb weight reduction compared to the OEM setup.

Constructed from mandrel-bent, TIG-welded 304-grade stainless steel, this system is built for maximum durability and performance. It’s fully compatible with OEM downpipes, all aftermarket downpipes, and the M Performance Exhaust (MPE) found on Competition models.

Features:

Largest midpipe on the market — full 4” diameter for maximum flow
Gains of 18+ whp and 30+ wtq when tuned
CAD/CAM designed flange for seamless flange-to-pipe transition
Handcrafted from mandrel-bent, TIG-welded 304-grade stainless steel
Smooth radius bends to minimize turbulence and maximize exhaust velocity
Faster turbo spool and deeper, more aggressive exhaust tone
Fits both right-hand drive (RHD) and left-hand drive (LHD) models with no modifications
Fully compatible with OEM mufflers and MPE Competition exhausts
RVNG Lifetime Warranty against defects and fitment issues

Compatibility:

2015–2019 BMW F80 M3
2015–2020 BMW F82/F83 M4
(Fits both LHD and RHD models)

FAQs

Answers to our most common questions below.

How Long Does Shipping Take?

All Rvng items ship within 1-3 days, if an item is out of stock the customer will be notified with the choice of a refund or an estimated timeline of delivery.

Do You Have Exhaust Parts For My Car?

We make a range of downpipes and exhaust systems for almost all BMW's. We choose to specialize in that market so we can always insure we are selling the best product possible for your Beamer!

Do You Offer In Person Pick-Up & Installs In Cali?

Yes, We are located in Garden Grove in Orange County, California. We invite any of our customers to pick-up in stock items and for any install or car related work.

Will Installing These Parts Void My Factory Warranty?

Aftermarket performance parts can affect your factory warranty on related components under the Magnuson-Moss Warranty Act — a dealer must prove the part caused the failure to deny a claim. We recommend speaking with your dealer or tuner. Our parts are precision-engineered to factory tolerances and we stand behind every product with our own Lifetime Warranty against defects and fitment issues.

Do These Parts Require a Tune?

Some parts — particularly downpipes, intake kits, and fuel system upgrades — will require or strongly benefit from an ECU tune to see full performance gains and to prevent check engine lights. Parts like heat exchangers, oil coolers, and hardware do not require a tune. We recommend reaching out to us or your local tuner before purchasing if you're unsure.

What Is Your Return Policy?

We accept returns within 30 days of delivery on unused, uninstalled, and undamaged items in original packaging. Custom or made-to-order parts are non-returnable. To start a return, contact us at rvngperformance@yahoo.com with your order number. Return shipping is the customer's responsibility unless the item arrived damaged or incorrect.

Are Your Catless Downpipes Street Legal?

Catless downpipes are intended for off-road and track use only. They are not emissions compliant and will trigger a check engine light without an appropriate tune or O2 spacers. If you need a street-legal option, contact us — we can discuss catted alternatives depending on your platform.

How Do I Know This Will Fit My Car?

Every RVNG product is developed and validated on the specific platforms listed. If your exact build year, model, or configuration isn't listed, contact us before ordering — we'll confirm fitment. We stand behind every part with our Fitment Guarantee: if it doesn't fit as described, we'll make it right.
