Mild Steel Or Stainless Exhaust System

[azza26]

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

If I was doing it I would go the MS, it's cheaper and by the time it rust's out you will have long since sold the car or upgraded it further.

[azza26]

very true, I might as well go the MS and spend the dollars I saved on another mod of some sort. cheers mate

I've had a MS system on the car for 10 years. It has a couple of weak spots in it now, but it's lasted well.

[azza26]

cool, yeah i've decided to go MS. Thanks for the input

[sinistaGTR]

look on amn ebay...S/S ones will be shitloads cheaper.... check out the xforce ones etc, bolt it on yourself

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.

A second hand exhaust is the go I picked up a 3 inch apexi cat back (stainless) for 350 on my 32 search eBay sometime decent stuff pops up

[Rolls]

Go whatever is cheapest.

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

this is bit off topic here but will a 3inch cat that has been clean out inside ( all the middle taken out) create any issues with back pressure?

[89CAL]

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

[N1 RB26]

on a stock 33 yes more than likely but on a hotted up engine making big hp then yes it would it's all relative to the car

[AngryRB]

yeah ok.. good point.

Yeah makes more power.

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.
