i was looking on ebay for a HR y pipe when i came across the aftermarket JDM high performance y pipe for the 370z..it looks like it could clear the front diff on the X's..id like to get someone elses opinion because im sure its much less restrictive then a oem HR y pipe..if this fits its another Y pipe for the X guys!! heres the link from ebay i saw it on

heres a pic

 

I am not sure but 250 is extremely expensive. You can get a used one with low miles for 100ish

 

ya but wouldnt this have better gains and flow then a oem HR Y pipe mated with test pipes?
