Hello Everyone,

I just purchased a new 2012 IS F a couple of months ago and am very happy with her so far. It's great to find a passionate group of people on this forum.

I'm starting to investigate options for increasing performance and have a question regarding the Joe Z Exhaust system. I certainly understand the performance boost, but what are the trade-offs in terms of interior noise or vibrations? Is there a break-in period? Do i need a specialized shop to install it properly?

Your answers are greatly appreciated!

James
