Hi folks, I am going to be buying a new system for my r34 gt-t next week and I am wondering if I should go a mild steel or stainless system? I am trying to work on a pretty tight budget so I was leaning towards the mild steel system. I have a quote for both, ms fitted - $1,100 and ss fitted - $1,800. Do these prices sound reasonable? can I get some advice on pros and cons for each system? any info would be really appreciated. cheers Aaron

p.s if anyone knows a decent place to have the system done on the Gold Coast please let me know. cheers

you could source a good quality jap brand for half that price second hand,

i got a 3 1/2 inch catback for $200 in vgc ( HKS hi power silent equivalent) i dont think x force is that brilliant either, the dump pipe looks a bit small at the mouth, best sticking with jap stuff not aussie stuff

Those prices sounds like too much. A mate just got a two into one system from the extractors back fabbed for his vk 304 and it cost $250. He supplied the muffler. Pipe is worth bugger all and to run a single pipe under the car should only take a couple of hours to cut and bend and weld it up. I prefer mild steel as it wont crack as easily as stainless.

Haven't got a bad thing to say about my x-force 3" MS exhaust. Sounds good, hasn't been restrictive and hasn't had any issues in the last 3 years

well my tuner said its quite average and thought it was holding the power back, there is a difference between it and others ive seen , maybe 2-3mm narrower than the actual flange if that makes a difference.

nothing wrong with mild steel as an exhaust material. in fact it has some benefits over the stainless that's generally used. the mild steel used is generally slightly thicker wall which will hold heat better and give a nicer sound. definitely consider buying a used jap exhaust though. can save a lot of dough that way.

what about titainium exhausts is there any benefits other than weight??

MS is fine had no problems with my twin x-force on the stato and no problems on my 32 with the jap rsr invidia exhaust

Go read in the x-force traders section the article on backpressure

And also, the turbo is the primary restriction on a turbo car. You want to have as much gas flowing after that as possible. AFAIK you could run a 5" exhaust on a stock 33 and it'd be no different power wise to a 3" exhaust

Or am I wrong? If so, damn I've been way off for years lol

It has pretty much the same conductive properties as steel so heat transfer would be similar. It has a much higher melting point so theoretically should last longer as an exhaust - in a hostile environment. It is probably a bit more stable when heated, it has a lower expansion coefficient.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
