350Z HR Y-pipe installed on a 2003 G35
#530
I'm still on the fence with the XYZ pipe. I've seen one dyno (Dynapack) showing some pretty solid gains from 4000rpms on up (about 7whp) with a pretty substanial loss of power below 2700rpms. I need to see at least one more dyno, preferably a Dynojet, before I consider yanking the HR Y-pipe. I don't like the idea of loosing around 15wtq/whp in the range that the car must launch in.

Yeah... I think I'll be stickin' with the HR Y-pipe.. since there seems to be obvious fitment issues with the G35x and the MD XYZ pipe.
I like the stainless steel Y-back VQ system though... will wait to see what the dual tip rendition of it looks like.
Otherwise.. I'm very happy with the sound of the OEM system we've managed to piece together here.. thanks Dave!

Looks like the HR Y-pipe might be worth a few HP and possibly inline with the gains from the MD XYZ pipe, but with no loss of power in the lower rpms.

Maybe this winter. I plan on replacing my wife's 98 Legacy GT wagon with a newer turbo LGT wagon. I may hold on her 98 LGT for about a month while I attempt to install the headers on my G. I just need to source them and the OEM HR cats.
