************SOLD************
I am selling the HR Y pipe from my previous 2008 G35 sedan. The flanges are rusty but I will clean them up. Otherwise all the heat shields, flex pipes, and vibration dampers, are intact. $40.

 

FYI the 07-08 G35 sedan HR Y-pipe is not quite the same as the 07-08 350z pipe. However, if you are installing this with the stock G35 exhaust, the midpipe outlet will match up better since it measures 2.25" I.D. The cat inlets measure 2-1/16" I.D. (just like the 350Z HR Y-pipe).

 

Is this the same measurements for the g35 coupe??

 

Stock cat outlet is 2". Not sure about the stock mid pipe since I don't have mine anymore. So the HR Y pipe matches the stock cats at least.

 

The coupe midpipe is 2.5.. so I would need the y pipe from the hr350z with 2.5 y pipe??

 

Where are you measuring 2.5"? Inner or outer diameter? My measurements above are inner diameter. The 350z HR Y-pipe is supposedly 2.45" inner diameter at the midpipe outlet.
