If you are happy with your current setup all you would need is the Y-pipe. If you are interested the straight pipe he made will have a resonator and be 3" in diameter.

When the first one shows up later this week I am going to go over and see it and will take pics as well as try to record the sound.

 

OK, he got the prototype of the y-pipe and straight pipe back, here are picks of them installed. This is not my car as I already have a Fujitsubo installed https://my350z.com/forum/showthread....threadid=21928 I ordered before I met up with him so no a reflection on his straight pipe or soon to come muffler.
He will do dyno's next week again, one of the car stock, another of just the y-pipe and rest stock, then one of the y-pipe with straight pipe and stock muffler and finally one with the y-pipe and straight pipe and muffler.

The wieght of the y-pipe is 4 pounds less than stock and the straight pipe is 4 punds more than stock so both together are the same weight as stock. He will provide an option with Jet Hot coating, I should know final pricing later.

 

Nice looking Y-Pipe! Is that 60mm merging into 80mm? Looking forward to Dynos.

 

I think it is 2 1/2 into 3, which is basically the same.

He said dyno's should be next week and I asked to go as I want to Dyno mine as well to where I am at with my mods so I will see how his does.

 

Looking forward to your report .

 

Not yet, the guy got tied up last week and was working on his drag car tuning it, so we couldn't make it to the Dyno with the Z, but we have a slot at the Dyno for Wednesday morning, so we will see.

I am going to put mine on as well to see where I am at even though I don't have a base dyno.

 

As the updates come out, let us know. I would assume this application would basically be the same on the G35 COupe? I would think the systems would be basically the same up there, just different cat-back?

 

Well we did dyno's today and will have him give me the charts as well as the final pricing for y-pipe, straight-pipe and muffler. I amnot sure about the G35 but I will ask him because I know he did an install on one already, the guys just wanted a better sounding system.

 

so what were the dyno #'s?

 

cricket...cricket...

 

I am sorry I missed the replies, it has been a couple of hectic weeks, the guy gave me the dyno charts and pricing and I will post everything tomorrow, basically it went from 237 to 248 HP with y-pipe and straight pipe and there is pricing for each individually and group purchases.

 

Westpak,
Thanks for the follow up. I'm looking forward to seeing where the additional power comes in and how far across the rpm range it helps. My suspicion is that it will probably help from 3,500 or so on up to redline which is nice.

 

I posted the final info here
