EVERYONE should put the 07 HR Y-Pipe on their Gs. I just finished the installation and I am very happy. The exhaust sounds a little more exotic when you get on it, and a little quieter at idle. I feel more power in the mid range and when I slam gears I can feel a difference (Butt Dyno). Thanks for the write-up DaveB!

Today I confirmed that the HR factory headers will indeed fit the VQ35DE as long as I use the HR cats (which flow a lot better as well). HR manifolds and cats are going for about $200. My car is going to be "Factory Frankenstein"

I bought my Y-pipe for $100 shipped.

Got my HR pipe put on the other day. Not sure what my thoughts are yet. Maybe it's because I already had HFCs put on that it's not going to be a big enough difference. I'll have to drive the car around a bit more to give a better impression, but I *think* the exhaust is a tad louder. However I might just be telling myself that, lol.

Closed the deal on my350z.com for an 07 OEM Exhaust (Y-Pipe back, no cats) for $100 picked up locally. The guy wants the whole exhaust out of his garage so I'll pick up all the parts and sell the mid-pipe and muffler for cheap to someone locally. Looking forward to hear, feel and see what this mod does to my ride.
