EXHAUST BRACE INCLUDED

DEEPEST TONE POSSIBLE AND LARGEST EXHAUST FLOW ON THE MARKET

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

The Rvng Designed 4 & 4.5 True Single Valved Exhaust System (G80/G82) S58 is engineered to deliver exceptional airflow, aggressive sound, and race inspired performance. Featuring a massive 4.5-inch mandrel bent 304 stainless steel exhaust, this performance exhaust system maintains a true single design from front to back, reducing restriction and improving exhaust velocity for faster turbo response and increased performance.

Its intelligent valved exhaust system gives you the best of both worlds. With the valve open, exhaust gases flow through the unrestricted 4.5-inch path, producing a bold, aggressive exhaust note. Close the valve, and the system redirects flow through a quieter route, providing a refined driving experience with minimal drone during everyday cruising. Finished with RVNG signature quad perforated tips, it delivers both premium styling and outstanding performance.

Enhance your performance build with the Rvng (F80,F82,F87) Upgraded Heat Exchanger for improved cooling and reliability under demanding conditions.

Please not the valve and pipe near the valve is 3.5 as its impossible to create a 4.5 valve.

Features:

• First and only 4.5 true single exhaust for the G80/G82 platform
• Valved system Switch between aggressive, free-flowing sound and a quieter, refined tone. Our system utilizes oem valve functions just remove you oem valve and put it onto the system. Our systems are compatible with all aftermarket valve controllers but in our opinion the cleanest way to open the valve 100% while maintaining oem button function is through softwares likes Bootmod3 and MHD

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.
