Hey guys,

Just wondering what exhaust system do you have in your Stagea. I'm looking to upgrade my stagea after I upgrade my Turbo....

I was looking at the HKS Hi-Power 409 cat-back exhaust system and a Xforce cat....front pipe will be a 3 inch one but dunno what yet (JJR, buy one from ebay, or some other name brand)

Would that a good setup in your opinion

Is they anything else you guys would recommend

custom 3" catback with mild mid muffler and stainless magnaflow oval rear... best daily driver exhaust possible... which will be sold from my car when i sell my car, as the sooner i go back to a standard exhaust the sooner i stop getting nasty looks from neighbours in my apartment block lol.

Just Jap Racing 3" bellmouth stainless steel turbo-to-cat dump pipe

Random Technology 3" stainless steel hiflow 620cfm metal cat converter

3" cat-back straight thru pipe to Kakimoto GTR Racing 3" straight thru muffler

sounds fkn awesome

isnt loud, isnt toney, isnt bassey, isnt deafening, doesnt have noticeble drawl thru the cabin, no headaches, no earaches

sounds H O R N

as the boost rises the power rises, the gasses come out unrestricted but yet muffled enough to tell its a tough RB25det in a shagn wagn

can any of you guys post up a pic of your exhaust sitting on ur wagz? im semi keen... but not after a cannon or ne thing... just a nice plush pretty much not even noticable... no noise or wank factor needed.

the pic attaches is what im kinda after... maybe not even that out there. cheers

Have just fitted a JJ 3" bellmouth dump and X Force hi flow cat. Cat back is as imported. 3" witha small mid mount and

Fuji Cannon.

Have been keeping check on fuel consumption and am using 2-3 litres less per 100. Breathes much better and power is noticeably better and smoother, and comes on quicker. I also use an electric controlled two stage boost controller, which is great for mountain roads.

im hearing ya. im after keeping the stock look ... upgrading the cat and cat back but i was the tip looking very much the same but bigger of course still want the twins out of the muffler .... hunting on down now ...trying to find anyone who just does the the cat backs so i can get it custom made to fit the stagea ! cannon is so popular no one is making anything else !

mine looks stock and was made locally... i will try and remember to take a photo tomrorow.

will sell exhaust seperatly when i sell the car if wanted...

I have a fujitsubo exhaust which as a mid and rear muffler (same as Alexcim's) and am very happy with it... The more power I made the louder it got but just cruising around town it wouldnt be much louder than stock but has a nice note when you open her up! sitting at a set of traffic lights you wouldnt even know it was turned on.

Does not look aftermarket at all.

So far it has pulled an easy 265rwkw so it makes the power as well..

Just got the Just Jap 3" bellmouth front+dump installed yesterday on an already 3' HKS Super Drager catback.

It spools up slightly louder, and it did exactly what I thought it would do - at about 2.5k its just that little bit smoother/quicker, and it just seems the car can breathe easier. For 200 bucks, you can't really beat it!

  • 3 months later...

ahh finally exhaust is on, and pics have been taken

JJR front/dump from just jap. didnt fit up right need to be cut and re-welded, the bend is wrong and hits the crossmember

3" Xforce hiflow cat

Xforce MID muffler

Xforce read muffler with twin 3"tips

    • 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.
