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.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
