Buying Intake & Exhaust
So my uncle wants to buy an intake, header & exhaust system for his 2004 350z roadster and he put me in charge of getting information on it. His preferred brands are HKS and obviously NISMO. He wants to replace absolutely everything on the exhaust side of things to get a little more growl out of the car, and also hopefully some more power.
So we were thinking:
Intake:
HKS Racing Suction Kits
http://www.hksusa.com/products/?id=1445&rsku=5934
Header:
Nismo R-Tune Headers
http://www.nismoparts.com/catalog/?section=382
Exhaust:
HKS Hi-Power Exhaust
http://www.hksusa.com/products/?id=715&rsku=5969
http://cgi.ebay.com/ebaymotors/HKS-H...25923863QQrdZ1
so my questions are:
will all these products work together just fine? I would assume they should fit the roadster just like they fit the hardtop. Also, will the nismo headers, work with the hks exhaust? We want to replace the entire exhaust, so between the nismo header, and the hks exhaust, is everything replaced? Or is there a catalytic converter or something that we can replace with a straight-pipe as well while we're at it? (we're not worried about emissions laws or anything like that)
Any input would be greatly appreciated and i'll make sure to get some sound/video clips as well as pictures on this board once we're all done.

I think for the intake ur spending far too much for a product similar to cheaper ones. I think the HKS intake is shortram.. ud probably get the same gains from a 100 dollar JWT intake which sounds awsome might i add.
The headers are good but Crawford makes similar ones that performe jus as well or better than nismo (made by fujitsubo i think) and cost less (i think..)
The exhaust is awsome choice.
JWT Popcharger
Crawford Headers, Crawford Hi-Flo Cats
HKS TD Hi-Power exhaust
With those options.. the estimate cost would be..
109 shipped for intake from avalon racing
~700 (guesstimate, mite be more or less) for crawford headers
450-500 for crawford Hi Flow
1450+shipping+long *** wait for HKS Exhaust.

[ HEADER ] == [ CAT ] == [ EXHAUST ]
so what i need is
[ CRAWFORD HEADER ] == [ STRAIGHT PIPE ] == [ HKS EXHAUST ]
now i'd obviously like everything to be the same diameter piping (preferably 60mm), and if there are catalytic converters to replace, i may as well do a straight pipe or test pipe or whatever its called. Does crawford make a 60mm straight pipe, or should i just get a muffler shop to make one? Also, what is the diameter of the outlet on the crawford header?

the diameter of the HKS exhaust is 60mm or 2.36220472inches, and the outlet of the Nismo Header is only 2.25inches or 57.15mm. It would be perfect if i could find a header that has a 60mm/2.36220472inch outlet, and a matching straight/test/off-road pipe to join the 2.
Dillon is rite, nismo parts are over rated. Only one i'd go for are the wheels.
Yes, if you want a FULL exhaust system u'd want to get headers-cats-cat-back exhaust. Most people change the cats cause they're the weakest part of the car. Most people actually don't do headers b/c they're expensive and you barly gain squat (compared to other mods). the Cat and the Y-pipe are hte weakest part of the exhaust system, which in general is pretty good to start with.
If I were you, i would do Cats, exhaust, intake and plenum mod. W/ those you can get about a 15-25 hp bump, depending on your car and engine.
I noticed you used straight pipe instead of Hi-flo cat. They're 2 diff things... Straightpipe is a pipe...w/o any substrate for breaking down emmisions. It makes ur car smell and rasp when cold or revving, even w/ resonated ones. I dont think ur uncle, from my experience w/ older folk, would like it.. Stick to hi flow cats.
Plenum mods are best mod by far... you can either get a full plenum like crawford or APS tallboy or kinetix Vx series., or spacers like motordyne, skunk2, aam ect, or a full upper+lower plenum upgrade like kinetix SSV. Expect about 10-15hp from any one of those... (on a stock car)
Exhaust... if it increases the midlpipe and Y-pipe diameter to 3 inches or is TD, they all provide same HP increase on an NA car, so u can get any one depending on the sound. HKS, nismo, fujitsubo, amuse, top-speed, greddy are all popular ones.

okay, so for now lets say this is the parts list:
JWT Popcharger
Crawford Headers, Crawford Hi-Flo Cats
HKS TD Hi-Power exhaust
where does the Y-Pipe come in? Again, we want to replace the entire exhaust system. In my province there are no emissions laws, and its not illegal to run without catalytic converters, so we'd almost rather have a nice high-flow resonator than a high-flow cat.
but back to my other concern, piping diameter, i'd like it all to be 60mm ideally (or higher) so it matches the HKS exhaust.

If this is an NA car, I would ONLY add a JWT Pop Charger.

what about the HKS Rotrex Supercharger set-up?
other question, that plenum mod, is it going to change the way the engine sounds? not that it matters, i'm just curious.

Course it will. Mine made it sound more like an american v8 but quieter. HKS Rotrex=weak/reliable. Michael is very right about the TT.. but the setup i gave you w/o headers would set you up for turbo also.
If your province has no laws, get resonated test pipes. Laboree makes a good set, as does megan, kinetix. They sound good and have a nice boost in power.

any specs or links on any of those products? i think i'm starting to narrow things down a bit better.
any idea what the outlet diameter or piping diameter of the crawford header is?
also is it Labree, or Laboree?

i want everything to be T-304 stainless steel (or titanium) and i want it all mandrel bent (no crush bends)

Skip the headers - do not bother till you do cams
Exhaust - pick your poison, all are about the same (HKS is a very setup)
intake - also makes no difference, so pick what you want

The HKS air suction kit is a good quality piece, but for the same quality and same power gains I would take the JWT Popcharger and you could get the motordyne plenum spacer which will give you some more power all that for the same price of the HKS air suction kit. But if you want to spend a little more for the plenum I would go Kinetix SSV Manifold all the way.
I would take the Crawford headers over the nismo they are both good quality, but they are others out there that won't empty your pockets as fast for the same power gains.
I would go Megan all the way for test pipes if your not worryed about emmisions.
Then I HKS HI-Power Exhaust all the way.
But at the end you buy what you like this is just the route I would take. I would look at mynismo.com and call them up and ask for Jason he can get almost any thing for the Z.

since i'm most likely not doing the headers, i only have a couple remaining questions. does anyone make any titanium high-flow cats or resonated test-pipes? Will they give me a CEL? (my mechanic friend seems to think so) And if there are no titanium ones, which ones are at least T-304 Stainless steel & mandrel bent?
