Hey guys, recently i got an exhaust fitted to my car, it is a 2.5inch cat back with a 4inch canon, when it is cold it makes a loud clicking noise, not a mechanical problem, it just makes it sound like a old corolla with a shitty exhaust. is this due to loss of air flow? even though the pipe is only 2.5inch...? anyone get this sound from their exhaust? anyone know what causes it? shouldn't it be a deep tuff sound? :blink:

Could be because it is a new exhaust. They take awhile to "bed" in. Some have a burning smell, some make noises.

So you're saying i should just give it some time and not worry too much?

Clicky sound? or is it more like a rasp around 3500 revs?

Haven't measured what revs it happens around, i'll have a look tonight, i'm pretty sure that it is the note it is giving out though.

Anyone else?

i also have a 2.5 inch cat into a 4 inch canon

i get it aswell

its around 3500 rpm and stops about 4000

however if i give it the beans it goes all the way untill 7000

i will take a video and youtube it for example tonight if im bored enough and post it.

i have been told that most NA skylines will get it and it something to do with the resonator.

p.s i recon it sounds tough when it goes to 7grand just getting faster n faster.. its something different.

You dont have to deal with it guys!.. just dont buy cheap generic exhausts! They will do nothing for it but make it worse!

Last year, I had to move to a new place where now I am living. It was very far and where I had no TV to watch and no film to see and no library to read. I had nothing else to do. Life then to me was like a desert.

However, to my great surprise, I found a web bar, which was very far from the place I lived. I entered the bar that day. It was from then on that I began to immerse(使陷入)myself into Internet.

When I first came into the bar, I didn’t know how to access the Internet. With the help of others, I opened a homepage(主页), finding it was full of colorful and rich contents. How interesting it was!Clicking the mouse, I set up my own e-mail address under the guidance. I read sports news, entertainment news and all kinds of much other information.

I was becoming happier and happier. On holidays I sent e-cards to my friends to express my greetings. I also bought several books through e-business and ordered free e-magazines, which were of much help to my study.

Hearing that finding a job on Internet is very efficient, I am ready to have a try.

I was and am being benefited from the Internet, which makes me realize that the quality of life is as important as life itself. With the company of the Internet, I will never feel idle(闲着的) any more

Someday in the future we may not need to have money in our pockets. Is life easier when people don’t need to carry any coins or currency at all? Is money heavy to carry? Is it safe to carry money? Maybe in the future each of us will have only one small plastic credit card. We will use it to buy all the things we now buy with money. We will not need money to pay for things.

Of course we may still have some of the same problems with cards that we now have with money. Sometimes we lose money. Maybe we will lose the card. People steal money. Maybe someone will take the card. Someone may even make a card that looks like our card. Since we can’t buy anything without our card, the credit card may be no better than currency. 

Is there something even easier to use than credit cards? All of us have a thumbprint. No two thumbprints are the same. Maybe someday the government will keep people’s thumbp

    • 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.
    • 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.
