Are exhaust systems compatible?
The exhaust system layouts of the 350Z and G35 are very similar. However, since the G35 is a few inches longer than the Z, the exhausts are not directly interchangeable. Aftermarket exhaust systems designed for the 350Z will need to be lengthened approximately 6 inches to fit on the G35. Most exhaust system shops can do this for a small fee, while some of the exhausts actually come with a lengthening pipe ready to bolt in.
