Hey. I'm about to buy a Nismo Exhaust. Comes with Muffler+midpipe. I have a G35 Coupe. So I know I need the G35 Extensions. Now I need a Y-pipe. Can I use an HR Y-pipe on the Nismo Exhaust? I was under the assumption they had different sized piping...

If not, what should I be buying? I wont be getting HFC's or anything...so I dont know if the nismo cracking issue will be applicable to me.

Let me know what you think. I'd appreciate some help.

Thanks in advance.
