Straight EXHAUST for F82-M4
FBMW F82-M4 exhaust development has started.
As the first step of the development, a middle pipe and a straight rear silencer were fabricated to collect data on engine characteristics.
We did a test run, but the exhaust sound was not product-ready in this condition.
We are developing the product to be able to handle the expansion of tuning by testing with boost pressure of 2.0K or more.
