Hey ive recently been quoted a price for a 2000 skyline r34 GT non turbo, for an exhaust system. I was wondering if its worth the price, and if the components are any good? The quote is below.

You will be looking at $1150.00 complete for extractors, stainless 100cpi hi flow cat and 2.5" system.

Thanks man I'll look into it. Also, if I'm planning to upgrade to turbo when I get off my p's will a 2.5" system with a 4" cannon be sufficient? Or will I have to upgrade?

What's CPI mean? The exhaust system is 100cpi is that good?

search my friend search lol... theres a full section bout upgrading NA 2 turbo...

and btw if the system u got quoted for has no mufflers or resonators??? on an NA that kinda exhaust on any car is gunna be well over the 100db mark, legal limit is 90db at 3k or 3.5k rpm......... but hey its ur preferance lol

best bet u can go for is get a big single tip or twin tip with a good brand muffler, 2.5" mandrel bent system (mild steel 1/2s the price n sounds better), dun worry bout hi flo cat, and finish it off with a nice set of extractors

its really up to u tho and what u wanna do with the car... like depends if ur gunna keep this car n make it a beast by pouring money into it or sell it a year down the track n upgrade

You can pick up some sweet almost new rear mufflers to suit your application form exhaust shops/wreckers, lots of people upgrade their exhaust and leave the old stuff behind, A rear of any newish Nissan turbo should suit (R34) or a 6 cyl Ford or Holden.

how long until you get off your p's? the reason i ask is that if it isn't that long (like a year or so), i wouldn't bother doing extractors. just get the catback. save the money for the turbo upgrade as you will only have to ditch the extractors when you put the turbo manifold on

most expensive JDM exhausts come with a cannon. majority of cars on this forum have a cannon. owners choice.

1150 sounds fine, extractors are the most expensive part. try get the exhaust shop to supply all components as if you supply your own cannon they are likely to swallow the costs where as they would probably supply a decent muffler included in the price if you didnt :)

ask for a hotdog in the middle too, should make it sound nice. GL

I have a year to go then I'm off my p's. I will be putting a turbo in when the time comes, I just want to be ready for it. So you don't have extractors when you have a turbo? Wow thanks you saved me a heap :)

that is my intention, yes. I wanna keep the car and put money into it. I'll be having it for a long time, so I'll try make it last :)

the exhaust manifolds are completely different. i found a few pics to show you what i mean. the NA system i am showing is off a rb30, but it is pretty much the same as a rb25 or rb20.

rb25 turbo manifold. you can see where the turbo bolts to

rb30 stock manifold and extractors side by side. note where the front pipe meets the headers on the stock setup. totally different location to the turbo manifold, and on the extractors are 1 piece

GTScoT, do you think that lancers with cannons, or hyundais with cannons, or even commodores with cannons are ok? most people on this forum will say no that is stupid, but will then put them on their car. somehow the rules don't apply to them. it is either all or none. i personally don't mind the cannons on any car (have owned 3 cars with cannons, one 1 i put on, but that was because it was part of the exhaust system i bought and couldn't be bothered spending the money on a different muffler) provided the right type is used (and if need be with other mufflers/resonators) to get a decent sound, however if i was building an exhaust system from scratch i wouldn't put a cannon on, not even on a skyline.

Cannons try to make a small engine sound bigger / more powerful than it actually is by using loud annoying drone sounds that fall far short of the bigger engines they're trying to imitate. If cannons were cool and actually made a good sound, V8 vehicles would have them - fortunately they don't. I'm paying good money to get rid of the cannon that came with my car. In fact, I'm scrapping the whole system because like alot of vehicles with cannons the whole exhaust is pretty poorly thought out / designed.

The best exhaust system I've ever heard on a small displacement engine was a Genie extractors and single muffler system on a 1.8 litre TA22 Celica...it ran 2.25" all the way through, with a 3 inch tip on the end. This thing actually DID sound like a small V8 (it helped to have .45 Weber side drafts and a nice firing order) as opposed to any piece of shit, lack-of-back-pressure cannon.

Some people like the sound a cannon makes though. And that's okay, because some men like other men.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Mistakes were made, my R34 Story

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
