Yup...I agree. Based on my past experiences with various other exhausts and all....I think that I really prefer using the OEM hanger locations and mounts. Custom mounts had a tendency to fail over time on me.
No I am not saying that the F.I. version will fail....just my preference.
I am still waiting with everyone in getting a H or X pipe option for the Nismo model. My Sunline H pipe has flanges that are misaligned and I have too many gaskets in there to compensate. And I think that it still leaks a little.
