E7hty Posted December 28, 2016 Share Posted December 28, 2016 Hi again guys any ideas here ? Sitting on 110 miles and currently in the garage. Noticed it by chance really the bendy exhaust pipe near the drivers rear wheel I noticed surface rust spots all clustered in the one area maybe 6 inches long. Is this normal on a brand new motor never mind ST ? Cheers 1 Quote Link to comment Share on other sites More sharing options...
stef123 Posted December 28, 2016 Share Posted December 28, 2016 if its mild steel then yes, surface rust is literally just that - some salt spray left overnight on a piece of mild steel will cause it to be rusty by the morning. 2 Quote Link to comment Share on other sites More sharing options...
E7hty Posted December 28, 2016 Author Share Posted December 28, 2016 Not sure buddy it's the bendy part of the pipe which can be directly seen by the drivers rear wheel looking directly underneath. Is this liable to cause any problems. ie become worse gradually to the point of failing ? Quote Link to comment Share on other sites More sharing options...
stef123 Posted December 28, 2016 Share Posted December 28, 2016 I'm not familiar with the exhaust setup of your car but it will take a fair bit of corrosion to eat away at a standard exhaust to cause it to fail. Most factory exhausts are mild steel, given the exhaust heats up and cools down constantly and is also subject to water and salt they do become rusty quite quickly, especially around welds. You should be thinking about a new system from pipe dynamics anyway 1 Quote Link to comment Share on other sites More sharing options...
E7hty Posted December 28, 2016 Author Share Posted December 28, 2016 As long as it lasts me 4 years I'm happy ! It's mainly on an actual stretch of pipe. Perhaps the U.K. weather doesn't help etc You'd think Ford would mak OEM exhausts stainless steel. Cant really afford to put any uprated parts on it and I wouldn't anyway I'm happy with how it is in all honesty haha Quote Link to comment Share on other sites More sharing options...
E7hty Posted December 28, 2016 Author Share Posted December 28, 2016 I've sent a quick email to my dealer to see what he says to cover myself Quote Link to comment Share on other sites More sharing options...
isetta Posted December 29, 2016 Share Posted December 29, 2016 hard to say without a photo. my 2007 fiesta had a hole in the exhaust pipe about 2 cm forward of the rear silencer (not on the actual join) when it was only 4 years old. hole about the size of 5p coin. put some exhaust paste on a piece of biscuit tin type metal and held it over the hole with hose clip(worm drive type). When it was 5 yrs old I had to replace the rear silencer as it was splitting open all over the place. Very disappointing for the original exhaust on a car. In comparison my wife's 2001 Focus still had original exhaust on when we sold it at 15 years old. the rust on the exhaust looked terrible for at least the last 8 years but it never went right through Quote Link to comment Share on other sites More sharing options...
CREED Posted December 29, 2016 Share Posted December 29, 2016 The stock ST exhaust is mild steel so it will show some signs of surface rust. The tips are chromed so they are the only bit which should stay shiny 2 Quote Link to comment Share on other sites More sharing options...
E7hty Posted December 29, 2016 Author Share Posted December 29, 2016 Yes but it's done 130 miles not thousand. It's two weeks old. Are they built to last or is it just a terrible exhaust because they know people change it ? If I get 4 years out of it I'll be happy if not I won't be Quote Link to comment Share on other sites More sharing options...
E7hty Posted December 29, 2016 Author Share Posted December 29, 2016 Also I looked at the guy at the works Focus ST 6 month older yet his looks brand new compared to mine Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted December 30, 2016 Share Posted December 30, 2016 that looks perfectly normal for mild steel to be fair Most factory systems are mild steel, it isn't just ford or the fiesta. Surface rust can stay just that for years before it becomes serious Personally I went for a custom 2.5" Full system with sports cat made from T304 Stainless Steel = no rust for me. Lifetime warranty too 2 Quote Link to comment Share on other sites More sharing options...
Tuffers69 Posted January 1, 2017 Share Posted January 1, 2017 Thats fine itl last years, just be thankful its not on show! Every time i park my motorbike up the exhaust ends up looking like that! 1 Quote Link to comment Share on other sites More sharing options...
Paramanic Posted January 4, 2017 Share Posted January 4, 2017 nah thats normal lol if you want it to be shiny all the time upgrade to stainless steel exhaust :) Quote Link to comment Share on other sites More sharing options...
Ian Lanc Posted January 8, 2017 Share Posted January 8, 2017 Once read a while back were a chap took his whole exhaust system off his newish car and had it galvanised at a local steel engineering company!! Anyone had this done or thought about getting it done ? Would really extend the life of an exhaust! Quote Link to comment Share on other sites More sharing options...
Paramanic Posted January 9, 2017 Share Posted January 9, 2017 Depends on price as it's probably cheaper just to get custom or one of the top brands Quote Link to comment Share on other sites More sharing options...
Tuffers69 Posted January 9, 2017 Share Posted January 9, 2017 The problem with protecting the outside of the exhaust is that they don't rust from the outside in, it's the inside out due to condensation! Quote Link to comment Share on other sites More sharing options...

This is when galvanised comes in to play as the whole exhaust is dipped in the stuff, so every nook & cranny is protected, inside & out. Found out that my friend who's father in law owns steel fabrication and they do galvanising, so going to enquire how much it would cost to get a full exhaust dipped.
