got quoted today for 2.5inch custom exhaust 850 installed at western mufflers. mild steel excluding extractors.

might get those coby ones from partsco.

anywho went to BEL and got quoted close to 1700 for the following

coby extractors $360 (get this myself)

bigger cat $440

HKS 409 (forget the name) exhaust 900 bucks

which should i go with?

will the custom setup give me the same performance gains as the HKS?

How big is the HKS 409?? what size piping

i tihnk its HKS 409 Hi power or something like that.

I reckon the custom exhaust unless your willing to put up twice that amount and go 1700.

but im not sure how good the hks hi power is.

Edited by blk_sz

thanks guys,

yeah its the hi-power silent one i think.

2.5"

the guy at BEL said they would need to cut off 6 inches though becuase it is an N/A

think i might go with the HKS one, bigger cat and get the extractors myself.

installation by myself probably.

$440 sounds a bit expensive for the cat - should be able to do better than that if you look around

Definitely fit it yourself, it's not hard if you have the right tools (basically just a good socket set and something to raise the car eg ramps/jack).

I have r33 GTS4 n/a. with standard exhaust. I really wanna just put a canon muffler.

1. Got quoted $280 for Canon muffler + Instalation (Muffler is some cheap brand I guess?) is this price is right?

2. How loud will it be when I put this muffler? does it depends on how big it is? like 3" tip and 4" tip?

****I had a cat back exhaust system before 3.5" pipe and 4.5" tim canon muffler, went back to standerd as it was loosing power due to lack of back pressure. But now I need little bit nice beat in the car, not too loud, thats why I wanna put a reasonable cannon muffler (my cat back exuast system is for sale by the way http://www.skylinesaustralia.com/forums/R3...8#entry3582368)

1. Got quoted $280 for Canon muffler + Instalation (Muffler is some cheap brand I guess?) is this price is right?

the price is right if you are happy with the product, it's impossible for anyone else to judge without having a look at it. best you go to whoever is supplying you with it and inspect for yourself.

2. How loud will it be when I put this muffler? does it depends on how big it is? like 3" tip and 4" tip?

this is your typical "how long is a piece of string?" question. loudness will depend on what other components you have, the quality and material used in those other components and the cannon. mild steel? stainless steel? titanium? etc.

tip size does have some affect on how loud it is. as a very general rule of thumb, the bigger the tip the louder.

okay,

theres a group buy $155 high flow xforce cat.

650 bucks for 2.5inch mild steel exhaust (custom)

might pick up second hand extractors.

cheers guys:)

saw a guy selling 2nd hand coby's for $300 in the for sale section.

keep us posted and when you get a video clip, post it in the sound thread

eug

Finally got it all done yesterday!

and im happy with the results

the car pulls alot better through the rev range and i get more out of each gear.

as i went from mild steel to stainless cat back the car has a much nicer growl. before it just sort of droned then droned some more.

the car is alot more responsive which makes driving it a lot more fun!

the extractors smoked some what but because i had the wrapping and high temp paint on them the coby paint didnt come off..

ill put a sound clip up when i can be bothered..

end of the story.. im happy :)

    • 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.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
