riptide Member 733 Member For: 13y 8m 2d Gender: Male Location: Auckland, New Zealand Posted 06/02/12 02:27 AM Share Posted 06/02/12 02:27 AM I think I paid NZ$1500 for my whole system in stainless. Sounds a little loud and I would probably go stainless again next time but in twin 2.5". Lagging the front part of the system will keep the heat and noise down considerably.There wasn't much difference in the mild steel price where I got mine.

discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 16y 9m 27d Gender: Male Location: Probably above atmospheric pressure Posted 07/02/12 11:43 AM Share Posted 07/02/12 11:43 AM It'll depend a lot on muffler size and construction for any exhaust I'd think? My 2x2.5" mild sounds nice except when towing at 100, then it's a bit loud and droney. Rear muffler is small barrel style which I was recommended to change to a better construction stainless oval type. Link to comment Share on other sites More sharing options...
JGP Donating Members 309 Member For: 14y 23d Gender: Male Posted 08/02/12 03:33 AM Share Posted 08/02/12 03:33 AM Some more info, I asked Hi performance products in Mitcham who are a distributor for jet-hot and the guy said that if you want 'jet hot 2000' coating which is designed for turbo applications it only applies to mild-steel. So it seems I will be sticking to my original plan of mild-steel dump & cat with stainless steel from cat backextract from jet hot site:JET-HOT 2000JET-HOT 2000 is a coating that can withstand high temperatures over 1094C. This is a very high corrosion resistant coating, making it a very good coating for use on Turbo Housings, Turbo Manifolds, F1 race car exhaust and other Hi-Temp applications. The colour is Black.(This coating cannot be used on alloy parts.) Link to comment Share on other sites More sharing options...

In my opinion its a great option as it keeps the heat inside the exhaust and limits heat transfer.When I bought pacemaker headers I always had them coated Edited 08/02/12 03:48 AM by arronm Link to comment Share on other sites More sharing options...
JGP Donating Members 309 Member For: 14y 23d Gender: Male Posted 08/02/12 04:02 AM Share Posted 08/02/12 04:02 AM how much to ceramic coat? I was quoted 200bucks approx a metre for hi-temp 2000(approx 1100 degree celsius protection). I think the less performing coats are about $100 Link to comment Share on other sites More sharing options...

Its been a custom s/s 4in dump to suite the high mount & a gutted cat with a xforce 3 1/2 cat back with a straight through resonator at the rear. The new one will obviously utilise the front half but the cat back will be 4in mild steel with offset s/s mufflers. My only reasoning for mild was the noise I want from the car. WIll be all vbanded as well 1 Link to comment Share on other sites More sharing options...

If rust was major concern then they would of switched to stainless. If your tryin to save coin, or keep the weight down then mild steel is the go. If you want to impress your friends then stainless.your my mate and no ones impressed Weeeeeeee 1 Link to comment Share on other sites More sharing options...
