2005 G35c 6MT (before & after HR Y-pipe dyno)
#16
I just picked up a HR Y pipe from a 08 350z. Going to install probably this weekend.
Not to burst anyone's bubble, but couldn't it be possible you gained some of the HP from the popcharger/ztube intake you installed?
As you mentioned you did the dyno when you first got your car with no mods.
Just curious..

Opss sorry. Well then two thumbs up. Now I'm pretty excited to put it in. I was mainly getting it for the sound and some better throttle response.

The HR y-pipe I felt a huge difference right away, so I figured it would be at least somewhat notable on the dyno.

The air fuel was measured when I still had cats, so it will always run 1-2 pts leaner with cats. Now that I have test pipes and some other bolt ons, I want to dyno again soon and see what the AFR looks like.

I just put on the megan hr y pipe and when the car is warming up the engine vibrates a lot. has anyone else had this problem with the hr install. it goes away when the car warms up. on the OEM hr y pipe there are these circular rubber vibration dampeners but i dont know how they work and if they will fix this.

The HR version is better because it's got slightly larger piping/better merge/bending.
The XYZ pipe is fully optimized merge and piping diameter with full mandrel bending, it will give way more improvement over the HR y-pipe and maximize your power and torque too. No you will not lose low end power, you should gain some.
