MILD STEEL: Heavier, Rust's, Not as noisy, slightly more durable than stainless in certian condiotions (due to its thickness).

STAINLESS: Doesnt weigh as much, doesnt rust, a little louder, Just as durable as mild steel.

Mild steel exhausts preffer to live in dryer/hot conditions were wet roads dont exist. (when water/moisture hits a hot mild steel exhuast day after day, youl be lucky to see a couple of years out of it.

Hope this helps.

Stick with the sainless!

hmm interesting. i was offered a customed made mild turbo back system for approx. $900 with stainless exhaust, home made mind you. Then i went to a workshop and they said $1200 for a turbo back stainless. For a $300, is the stainless considered more favourable?

Stinless Lighter? Any system made here would probably use the same thickness pipe as mild steel, and would therefor be heavier.

A mild steel exhaust will last a few years 5+ if it is prepared proparly before being painted. Im sure new cars dont have stainless exhausts and they would last more than 2 years.

Stainless also has a more audible drone in the cabin compared to mild steel pipes i have found.

From what ive been told that Stainless Steal (SS) will be heavier

due to the mixtures of alloys & chromium, Weight wont be a big difference to lets say aluminium or titanium, Your lookin at 1-5kg difference.

Well i never really knew different metal made differnt sounds but the muffler itself, eg apexi dunk sounds different to a apexi n1, well it might be the case that different metal do make different sounds, but u gotta remember legal db level is 90.

Mild steal will rust & will last a good 5years+ if anti-rust was spreyed on the metal.

Quality of workmenship between of a custom made or workshop.

98% of the exhaust ive seen is MIG welded together, dont get me wrong MIG is fine (people MIG submarines together) & it doesnt take a genius to weld just a steady hand (easy 2 use, hard 2 master)

The only real advantage of a workshop is that they have all the tools & a hoist to easilly lift up the car without using jacks & jackstands, to be honest i cant see any real advantages if u go to either one, but the price. if the home doen job knows what his doin.

Hope this helps a bit.

From what I have heard, stainless has a more tinny sound. Depends on whats on offer at the time, my exhaust on the onld R32 was mild steel and that was on there for 4 years and was still fine. And you all know what the weather is like over here in NZ, and it wasn't even painted.

MILD STEEL: Heavier, Rust's, Not as noisy

not as noisy? surely this would have more to do with the actual shape of the exhaust and not the material. If you had a straight pipe running from your turbo made from stainless steel then changed to a straight pipe made from mild i doubt it would be less noisy if they both were exactly the same shape and size..

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
