Thanks for mentioning that. I was able to find it. It was interesting to read Tony's responses, especially that they consider how stiff the motor mounts and exhaust hangers are when designing a system. It's obvious they put a lot of thought into it. I guess I won't worry about that aspect. The videos of the FI 18" systems vary greatly in how loud it sounds. The one made by the fellow in Dubai sounds like it is REALLY loud. Others don't. The Stillen with factory cats doesn't sound that loud. I'm thinking I might stick with the Nismo until I can hear one or both of these in person. I can't afford to trial and error this at over $1000 a try!
