Hi Everyone, I have a 2012 G37xS Sedan and the stock Y pipe is rusted and leaking which is causing it to become so loud.

Looking for assistance on finding a replacement online! (looking for a good aftermarket replacement)

Thanks in advance!

 

The Z1 and ISR Y pipes are relatively affordable new aftermarket options.
I have an OE Y-pipe from my 2013 RWD sitting collecting dust. Not sure if it would be compatible with your xS, but if it is, and you're interested send me a PM.

 

One for sale in the classifies...... https://www.myg37.com/forums/private...cutek-spc.html

 

Same thing happened to mine about 2 years ago... I replaced it with a Megan Racing Y-Pipe from Ebay along with new gaskets & its been great ever since.

 

the 370z/G37 ISR is a popular choice because of its price point and larger primary tubing (2.75" vs 2.5")

Megan racing and Beluga Racing are also popular becaues of their budget pricing and does the job as a replacment y pipe

From there, you can get into the pricer y pipes. Motordyne makes an awd compatible single resonated one.

Hall Built Performance (HBP) makes a dual resonated y pipe.

 

I am in the same situation at the moment. I just finished installing my Fast Intentions RHFC, and moving that y-pipe around made it worse.

I can't decide between the ISR, Z1, or Megan.

I don't want raspy, and I want longevity. I'm leaning towards the ISR as I have heard the Megan doesn't hold up long in salt states, and the Z1 has more places for salt to hide in. Anyone have any opinions? Best performance would be cool too, but rasp-free and longevity are more important as this is my daily.

 

I made a video to compare the ISR, Megan Racing, and the HBP I had. I don’t know the style of metal each uses.

z1 now has a few y pipe options.
