370z stock exhaust on a 350z????

Reason I ask - I was thinking about purchasing a dual 2.5" titanium exhaust for the 370Z and fitting it to my 350, but I want to get some more ideas/insight before I spend $2500 or so (on something that's not guaranteed to fit lol)
I'd imagine an extention pipe would be needed just after the Y-pipe, but from what I've heard it sounds like the majority of the exhaust hangers are in the same place and some mods to the sway bar may be neccesary.
Thanks for any more info

Well, I could do that possibly, but I'm afraid the prices to do a custom titanium exhaust (with dual exits at the very least) would be be quite astronomical. Although, I really should just get a quote from a couple of local shops that are capable of doing so in my area and go from there. I might be able to find a shop willing to do a basic Ti system (minus Y-pipe) with minimal bends for a reasonable price, but on the other hand I'm afraid a place like Turbohoses (who do really nice work) would probably charge north of $6k 
If I were to have a custom ti exhaust fabricated, I would want a single 3.5" mid pipe into dual 2.5" mufflers and it will have to be reasonably quiet. Unfortunately this is why I'm not buying an off the shelf titanium exhaust for the 350, as pretty much all of them are 3" at best or are too noisy for my taste. At least with the 370, several of the Ti exhaust are dual pipes with ~2.5" piping...but it only makes sense to go that route if minimal modifications would be needed. I sent an email to Whifbitz in the UK (who makes ti exhaust) to see if he can maybe come up with something for me, so I hope to hear back in the next couple of days.
I probably seem a bit nuts, but I'm a bit of an exhaust ***** to say the least (and have a bit of fetish for the ting of titanium) and am trying to get the best sound, weight reduction, power potential as possible.

Lol I take that as a joke 
Paying that type of money for an exhaust system on a platform that's basically a decade oldis completely asinine. Not to mention that it doesn't sound/perform all that great since it only has an h-pipe.
Realistically, I'd like to keep it below $4k all said and done. If I did have a custom titanium system fabricated, I'd imagine materials would be about $1700 (with 2 DOC ti mufflers, few feet of 3.5" & 2.5" ti pipe, 3.5" ti flange, slip fit stainless Y-pipe, and connecting springs/tabs) and who knows what on labor. I would think someone could do the labor for $2000-2500 since the mid pipe would be pretty much a straight shot, and the stainless slip-on Y-pipe would make things a bit easier.
If I had my own shop and welder I'd just do it myself...but that's not the case at this current point in time

basically how it will sit ! it is wider than the 350z exhaust but it kind of looks like angry eyes in the pre set holes (note: it is going to be pushing on your bumper, so direct contact. it can be fixed if 1. remove exhaust tips and re position them. 2. cut the bumper 3.which is what im going is letting the heat mold the bumper away from the exhaust and then cutting all excess material out of the way, plus it looks like a flush fitment. )

clears the sway bar and drive shaft with more than enough room.

2. reving (pre warmed) it sounds deeper and less raspy with more of a warm up but i was in a hurry.

Thanks so much for that info/pics, TDD 
Very helpful!
I need to go over everything you posted and see what I think as far as trying to get a titanium 370z exhaust to fit. It's a risky proposition regardless, as the exhuast would be about 2300 shipped, and any additional fab work on the titanium can add up quickly :/ So I need to go over things carefully and come to a realistic conclusion lol. Thanks again though!
Here's the exhuast I've been talking about (i will have the Y-pipe chopped and 2 ti flanges welded on by the manufacturer - to minimize the restriction).
http://lightweightperformancetitaniu...iumexhaust.jpg
Edit: Btw, I take it the very rear exhaust hangers on the 370Z muffler line up properly (they're not wider apart like the exhaust tips)? Also, it's kind of hard to tell exactly where you had the 1 1/2" of additional piping welded in. Is it past the rear swaybar in order to get the muffler hangers to line up with the original mounts?

Sorry, I just have to agree this isn't particularly a good idea for people to do as even a "budget" modification. You can get a replica exhaust that will outperform the OEM 370z exhaust for less than $470, and sound better... so I don't see the point?
OEM exhausts are designed not based on performance, but on cost/sound deadening for the average driver/etc...
It makes sense to use some 370z parts on the 350z, this is just not one of them, sorry.
I don't understand why everyone wants to be "different," if you want to be different, do things that make sense to your car. 99% of car mods are dumb.
And... even if you have a built motor with cams, headers, and full straight pipes... no one is going to know what kind of exhaust you have unless you tell them...
A "sleeper" is something like an engine swap with super quiet exhaust and exhaust cutouts when it's time to pony up... It's not a 350z sports car with 10-20 extra horse power.
Props for experimenting though, I mean that's how we learn.

yeah stock cats hfc coming in soon but it sounds like that cuz it was still hugging on my bumper cuz the 370 dual tips are like 4' and i tried to re use the gaskets but ... there copper nismo gaskets so i have to buy a full set incuding the O rings for the inside of the exhaust

well i dont know if ur into actually working on cars in general or just ur z but i **** around with alot of turbo cars and naturally aspirated and with my short but knowledgeable schooling i had from high performance classes i already know stock is the best way to go all u need to do is take off all the little barriers nissan put in the way so the engine power is reduced ... its all done electronically and mechanically .... i dont get where u come off saying sleeper is a car with a engine swap ...... -_- a sleeper can be anything it could be anything ... its the aesthetics ! that makes it a sleeper ... for instance my car looking stock as ever nothing on the outside to even give the clue that its a performance car .... thats a sleeper ... and i read ur build list and u have one of those bad car mods ..... jwt pop chargers damage engines and even stalls them when they get to hot .... hps silicone intake tubing and gold dei tape drop in some performance filters and u got almost 10hp maybe more i dono ill find out when i do it but honestly as stock as my car is ... i just know that it will prob outlive me and hopefully my kids im just enjoying my z for what its made for but with a little mppfff
