DEEPEST TONE POSSIBLE AND LARGEST EXHAUST FLOW ON THE MARKET

RVNG 4.5″ True Single Valved Quad-Tip Exhaust – G80/G82 M3 & M4 

There’s nothing else like it on the market. The RVNG 4.5″ True Single Valved Quad-Tip Exhaust is the first of its kind for the G80 M3 and G82 M4 platform — engineered to deliver unmatched flow, sound, and performance.

At the heart of the system is a massive 4.5″ mandrel-bent 304 stainless steel main section, the largest diameter exhaust available for this chassis. By maintaining a true single design from front to back, we eliminate the turbulence and restriction found in factory and dual-pipe aftermarket systems. The result is faster turbo response, maximum exhaust velocity, and a raw, aggressive note that stands apart from anything else.

When the valve is open, exhaust gases take the unrestricted 4.5″ path for the loudest, most aggressive tone possible. Close the valve, and the flow is redirected through a quieter route for comfortable cruising without drone.

Finished with quad RVNG signature perforated tips, the system blends OEM-inspired styling with motorsport-level performance.

Features:

• First and only 4.5″ true single exhaust for the G80/G82 platform
• Full valved system for on-demand sound control
• Gains in horsepower and torque when paired with a tune
• Mandrel-bent, TIG-welded 304 stainless steel for maximum durability
• Smooth, uninterrupted bends for maximum flow
• Signature RVNG quad perforated tips (available in multiple finishes)
• Designed to work with OEM or aftermarket downpipes
• Designed and tested in the USA
• RVNG Lifetime Warranty against defects and fitment issues

Compatibility:

• 2021+ BMW G80 M3
• 2021+ BMW G82 M4

DISCLAIMER

IF YOUR CAR IS VERY LOW TO THE FLOOR YOU MAY WANT TO WAIT FOR THE 4” VERSION 

STOCK RIDE HEIGHT, H&R SPRINGS, AND MOST AFTERMARKET SPRINGS YOU WILL BE PERFECTLY FINE WITH THE 4.5”. WE ALWAYS COMPARE IT TO HAVE A NICE LIP ON YOUR CAR AND BEING A BIT LOW. YOU NEED TO UNDERSTAND HOW TO DRIVE DEPENDING ON YOUR SURROUNDINGS. THIS EXHAUST IS THE BEST SOUNDING AND PERFORMING BUT KEEP IN MIND IS THE LARGEST DIAMETER AVAILABLE, SO WITH THAT YOU WILL HAVE A LITTLE LESS UNDER-CAR CLEARANCE.
