This resonator delete is the best performance upgrade on BMW M cars.
You will delete 3 resonators . see the images .
It comes with spaces for your OEM exhaust brace. you can adjust the height.
This exhaust system upgrade was designed and engineered to work with most after-market exhaust systems/mufflers on the market today with only a single cut needed in the stock mid-pipe. It is a bolt-on that can be performed by most and the stock mid-pipe can also be reinstated if needed.
This system provides the maximum flow available and restores the sports car growl expected from a BMW M-Series car. There are plans for a future resonator upgrade for those who prefer a smoother sound to their exhaust systems.
