Tuning exhaust system Z4 e86 n52. Competent approach.
Tuning exhaust system z4 e86 n52.
In this form, we performed the following works:
set the exhaust sports manifold
removed the incorrectly installed X-pipe
implemented an X-pipe instead of a standard resonator
Also in the process they talked about some of the subtleties of gas dynamics when building a productive exhaust system.
These works helped the motor begin to "breathe fully" / increase power & torque by about + 10% L.S. from the drain.
Despite the fact that the catalysts have already been cut, the hostess of the car noted an improvement in dynamics at higher revs - the goal has been achieved!
