CEES Exhaust Bmw G20 330i Exhaust Pipe Assembly for BMW M340/M340i 3.0T 2019-2022 Stainless Steel Racing Catback Exhaust System

Product introduction Please see this is the original OEM exhaust pipe and our new performance stainless steel valve exhaust comparison, the exhaustinstallation position is 100%, want to know more, please contact me The original system used only one exhaust valve, but we installed a second exhaust valve in the system to get the most favorable results in terms of symmetry and overall sound. We can use a larger 76mm pipe diameter (instead of 70mm pipe diameter) to allow the flow of the entire system to be freer, especially when the two external pipe valves are open, the flow and sound are deeper and more fleshy, which is great. However, in contrast to the aggression produced by opening the valve, when the valve is closed, all the gas is forced into the muffler for muffling and discharged from the two internal tips, so there is no overly noisy buzzing. The factory price includes 4 perfect huge 102mm tips, available in a variety of styles. The exhaust device is bolted and can be easily and quickly modified. The package includes installation hardware.
