ok im getting my exhassut done next week after my coilovers go in this week and i get a wheel allignment, i have my own personal oppinion that you really only need around 2 inches of vaccum(back pressure) not as much as some people think, backpressure what for you need more on a carby engine to draw through the fuel but on an injected motor its being forced through via injectors and your afm measures how much air velocity is going through and it tells the injectors anyways.im getting from extractors back 2.5" mandrel bent im waiting on my high flow cat (2.5") but was jsut wondering i was thinking of going 2.5" inlet muffler with twin outlets and have the pipes on an angle coming out the rear because i thought my exhassut with jsut a cannon will be extremly loud?, my car probably only makes around 80kw atm all my mufflers are collapsed and who ever did my cannon oh god it goes from standard size to smaller. so it can breathe it goes good up high and thats about it, jut wondering from any of youse who might have had previous experince and who to talk to about a muffler or if i can find a twin outlet decent one not an ebay special, i know that all cannons do make it look pretty and the echo from them im getting sick of, i have read abit, but its always he said she said how the thread mainly starts,

extractors back 2.5" mandrel bent high flow 2.5" cataylitic convertor single 2.5" inlet muffler twin outlet to rear

thanks in advance

dont get a cannon...they dont look pretty either. get a nice simple twin tip setup.

mine consists of a 2.5" catback with two mufflers, one dual chamber one in the center and the rear one is a straight through leading to twin tips. i had it running on just the rear muffler with a resonator in there for about 3 days and i took it back cos it sounded awesome from the outside but the DRONE in the cabin was awful. it ended up sounding pretty neat, cost me $550 all up (mind you i didnt supply any of the stuff myself, was a scratchbuild)

a highflow cat will help too. which is on my shopping list :D

heres a pic of mine

well i went in there yesterday and he goes either 280 or 400 depends so i told him to shove it went down the road cat back with one muffler and a twin outlet tip 340

imo youl need another muffler, cos as i said the drone was unbearable, and youl prolly more likely to get EPA'd. otherthing is too it sounds just like a VL commodore with just the one muffler...quite gay.

im kinda regretting getting the second one put one cos since then iv gone turbo and could prolly afford to delete a muffler (turbo hushes things down quite a bit)

well im pretty pissed atm got my coilovers in went for a drive today turning a corner car slid on a loose surface tried to power out but i was already a passenger at that time wasnt trying to slide or anything hit a speed sign and rooted my guard ill post piks later, nothing rubs looks like crap now, and im going on a trip next weekend so exhausut is out of the question until after easter i would cop it if i was sliding or attempting to but i wasnt understeered snapped oversteered, so im trying to track down a front drivers side gunmetal grey guard

duno spring rates are 8 on the front and 6 on the rear came all setup and all good checked all the heights and everything ive got diamond back tyres and they get bad sidewall flex like didnt even try to slide hit sum bumps loose gravel car slide couldnt power out should have jsut hit the skids i would have looped it but not hit it oh well i know to be more cautious now so i think ill do the exhassut properly now once i get a new guard extractors and get it all done properly

yes i know i know dont need more ppl rubbing it in lol therye crap i know it ill get some more when i buy new wheels, well heres the damage new guard this week so its all good

post-55906-1238852220_thumb.jpg

lol its jsut cosmetic damage drives fine wheels not bent, jsut need some time to get used to the new setup becauase i tried to correct like i would if i had body roll and unresponsive steering lol, tht was before i polished it too lol very minor paint work came off weirdly i would have liked it better if i ripped by bar to bits just drill and zippy tie it for the time being

Hey,

sounds like a nice set up. i have same but with a resinator. dont no y the guy put it in, its comin out after the pink slip.

mine was 750 includin fitment of extractors, cat, and cat back system. i have a single tip on my hi flow muffler, it looks awesome in my opinion.

    • 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.
