I picked up a hr y-pipe (very good condition) from one of the members in this forum. The installation was pretty simple except that unscrewing the bolts and getting the old pipe out needed little bit of effort. It's really helpful if you use a hydraulic lift to keep the Hr y-pipe in the air to connect it with other pipes. The installation took me about 1 hr 30mins. Other than i had to remove the underbody panel (?), i luv this upgrade. The sound is a LITTLE bit deeper and louder but not that noticeable. But for sure, the car runs smoother !!

 

oh does anyone know what the black things are attached to the HR pipe?

 

Vibration dampners.

 

Did not realise that the y-pipe from the HR motor would fit the DE motor. Thanks for the post and photos.

 

Many people have done this mod IMO. I wish it was more louder though lol.
Only problem i'm facing is that i hear hissing sound after installation although i tighten the nuts tight. Tomorrow i'll go tighten it more with a longer bar but i hope this is normal

 

what other mods you got

 

I just have a JWT popcharger, MD plenum space comming next week, and ss clutch line. It's been like 3 months since i bought the car

 

Well hopefully u didn't pay a lot for that y pipe. Not worth it imo.

 

Actually, it's worth $85. After it breaks in, the sound got louder and i like it

 

Yea i guess its worth that

 

I like my HR y-pipe, but it was free so it was definitely worth it to me. I can't comment on the sound difference though because I put res. TPs on at the same time....

 

yea i'm running 2.5" berk test pipes and hr ypipe and it sounds horrible.. i'm waiting for the ups guy to show up with my new ypipe

 

i know that berk's have high quality stuff but IMO berk test pipes sound horrible. Not my taste

 

lol berk test pipes sound horrible??

all test pipes sound the same they're all empty, hollow pipes. It's what you mate them with is what changes the sound

 

Put straight pipes on any N/A car and it's going to sound pretty nasty and raspy.

 

They should sound the same but on youtube, berks' were very raspy, sounds like an expensive fart can..sry. maybe they had different mods on the car that they didn't mention in the description

 

use the one piece gaskits like the ones berk sells on here thos 3 ply gaskits reverberate, thats what your hearing, i had same problem till i switched it out

 

I used the gaskets that were on my car with stock system which are the ones that have 4 gaskets stuck together. When i bought the HR pipe, he gave me the one piece gasket that were on his 08 350z. Should i use that? Wouldn't there be more hissing sound because 1 piece gasket is thinner?

 

^^^ the stock gasket is fine. i just reused the ones b/t the ypipe and the test pipes but my car only has about 25k miles.

i was originally going to go w/ an HR ypipe until someone mentioned the inner diameter.
i'm planning on going aftermarket so will def want a 2.5 to 3'' outlet size ypipe.

 

yeah thats what i used and the problems went away i bought the nismo exhaust at same time so i had the nismo gaskit kit as well
