I was thinking about adding a set of HFC (Berks), but after doing some research, I found many of the coupes were having cracking issues with HFC and their nismo exhaust, specifically the y-pipe. Any sedans running this combo? If so any problems?

 

Is there a Nismo sedan exhaust in the US?

 

Sorry, I should have been more specific. What I'm using is a fujitsubo mid-pipe/muffler with a nismo y-pipe.
