These were on my 2011 G37 Sedan. They were installed on the car 01/2016 and have approx 60k miles on them. The driver's side HFC developed a hairline crack at one of the welds and was causing a small exhaust leak. I had a local exhaust shop weld over the crack and it has been good since. These do not cause a check engine light because they use the J-shaped o2 sensor defouler.
Car put down 285whp (CF: STD) on a dyno jet when paired with FI cat-back 18" resonated exhaust. Stock intake, Stock headers, Stock tune, 7AT w/ 3.692 FD swap
Selling because I just installed ISR test pipes.
Asking $325 shipped. Local pick-up available in DFW Texas area.

Hi i have a question, did they maintain the same volume when you installed them or did they get quieter over time. Curious because I just installed RHFC's and I dont want them to get quieter :[
