My Y pipe is getting installed at the dealer right now

 

I tend to agree with Dave... this sounds more like the Y-pipe off of a G37.. it has the shorter flex pipes... the heat shields are slimmer also.

interested in looking at the snaps of this y-pipe...

 

Alright I got the Y pipe installed at the dealer today.

Initial reactions after about 1 hour of driving. When I first revved the car I immediately notice the exhaust note was a bit louder and smoother - sort of more free flowing. There was about 20% increase in power in the lower revs (till about 3500k). On the highway I still felt the power all the way to about 5500k and shifting is a tad bit smoother esp from 2nd to 3rd.

Yes, there is some drone but I think it will go away after a week or two. I had the same drone on my new hks exhaust las year which became quieter in about a few weeks.

I need to see how this mod performs after the ecu adapts - probably by end of next week.

I love the exhaust note now as it is a bit louder but deeper!

 

Nissan must have 4 different versions of this pipe floating around. I know for a fact mine came off a 07 350Z. Yours sounds like the HR y-pipe I've seen pics off that came off a 07/08 G sedan which has much smaller flex sections and possibly smaller inlet pipes.

07 G35 sedan HR y-pipe

 

i have the hr ypipe of an 07 z and i'm happy with it

 

I got my Y pipe new using my friends VIN off his 08 VQ35HR 350z. This pipe has less flex section at the bottom.

 

I read an article mentioning the G37 sedan is a few hp down on it's G37 coupe brother due to exhaust differences. This could be it or it could be more marketing hype. But the Ys do look differerent and there's not real reason for that.

 

guys I've noticed something new today after installing the 08 350z y pipe. As I was revving my car to 2.5 to 3k then letting the car off completely, I noticed a hiss sound from the rear after letting the revs drop (foot completely off gas)... Now the dealer installed the part correctly with new gaskets... any clue what the issue is? Is the y pipe not broken in yet seeing it is brand new?

 

Well I learned that I got something else, lol. I feel like a jackass, but ah well, live and learn I guess. At least I didn't pay much for it, $20 local pick up.

I did a little research and found out whatever I did get is not a 350z HR y-pipe or part of a 08 350z exhaust for that matter.

Here is a pic taken from the craigslist ad of what I assumed was a 08 350z stock exhaust due to the title of the ad:




Here is what the 07-08 350z exhaust looks like:

so what did you get?

 

Looks like the sedan exhaust.

 

do any of you guys that put on the 08 350z HR Ypipe notice that it hangs down more than the stock exhaust or is it about the same? im really interested in this Ypipe cause i believe this could help quite a bit, but im worried about how low it hangs cuase im installing lowering coils in the next month or two...

 

second pic is what i have.

seems as if the sedan hr y pipe doesnt give the same results as the z hr y pipe.

remember reading here that some members installed the sedan hr y pipe and gave good feedback on it.

something is strange here...

 

I picked up the 2007/2008 VQ35HR Y pipe - http://nissan4u.com/parts/info/20020EV00A/

 

I have no clue. Maybe the sedan guys can chime to see if thats what their exhausts look like....

Yeah man tell me about it, lol. I dunno what I have but I might just order the Motordyne XYZ pipe instead, fugg it haha.
