This is a custom made cat-back exhaust to fit in a 335 (i or xi). This is coming off my 335xi which I'm selling.
The exhaust is in excellent shape, with no drone, and easily installs in a garage with just some ramps. You will use the 4 nuts and bolts from the OEM flanges to attach this exhaust to the downpipes, and the 2 OEM gaskets. Other than that it is all there and goes on all the OEM hangers.
