BMW M135i Downpipe INSTALL & Sound Comparison: VRSF
We recently got our hands on the 4" catless downpipe from VRSF to suit the N55 M135, M235 and M2 models. This is the install and sound comparison.
The car is currently running MHD and XHP tunes, these with the downpipe have really turned this car in to an angry little hatchback. Bloody awesome.
