Stopping down pipe rot!!
Hi guys. I'm trying to make my original downpipes last the winter and need to know the best way to go about it.. I've stripped all the rust in the past and sprayed them with high temperature paint but discovered they were rusting again; so I've now stripped them again, treated them with a rust converting chemical and have started to spray them up again (very thoroughly) with lots of thin coats. Does anyone know if there's anything else that can be done to save the pipes (I haven't got money to buy a nice stainless system atm)?
Thanks
Thanks

i know this isnt what you want to hear, but im afraid its true nonetheless.,,
they will rot, buy a stainless system.
second hand systems can be had for around 150 quid, sometimes cheaper.. just keep an eye on ebay.

Bugger.. OK, thanks for letting me know. I think i'm gonna see if they last the winter and then look for some when my bank account's not feeling the strain of uni.

as zimm says forget it, i've tried Hight temp paint and it rusts through, for longer lasting use plasticote stove enamel, but it rusts through as well, you can get it shot blasted and stove enamelled professionally but nothing beats stainless.

I chemically cleaned one system till it looked like stainless then primed it, and painted it with high temp paint, then cured it all evenly with a blowtorch
lasted 3 weeks till it looked shite again.

there are some cheap ones onebay around £190, you aint gonna get any cheaper for stainless, unless you get secondhand but then your looking around £150 mark.

Re: Stopping down pipe rot!!
Perhaps a ceramic coating would be more durable?

Re: Stopping down pipe rot!!
you could go for cermachrome you can get it in a tin but has to be baked on about 500 degrees C so best of luck and there aint many places that do it. http://www.soundrider.com/archive/servi ... atings.htm

Re: Stopping down pipe rot!!
After having gone through all the hassle of stripping the pipes right back and chemically cleaning, then priming and painting, evenly and curing properly they've lasted about the same as others have said. Rust started showing through after a couple of weeks of winter riding, now 3 months on and they look like absolute s@%t!! Mind you, any bike that's gets used regualarly in all conditions throughout the winter is going to to show signs of it pretty quickly but the pipes on the ZXR seem to be the biggest week point..

Re: Stopping down pipe rot!!
Get your hands on some ACF-50 mate, My zxr isnt out in the winter but my mates swear by it, its the stuff they use on planes to stop them corroding with the all the salt and toad they pick up.
Ive sprayed mine up whilst shes in the garage for the winter will see how she lasts come summer time.
Its a purple and silver can and u simply squirt it over the parts u want to protect then use a paint brush to smear it all over, it then stays on as a clear oily coat, u will see it burning off when the exhaust gets hot but it will still stay on the exhaust if u get me, only a couple of quid and its sold most of the big bike shops, i got mine at on ya byke in manchester.

If it's broke spray it with WD40, if it's still broke spray it again and leave it over night, if it's still broke, bin it.

I use scottoiler fs365, which is a similar product to acf 50. Has prevented rust on my bike this winter. Though my downpipes are stainless, realistically ure standard pipes will rust, it's only a matter of time till ure gonna have to replace them really, so start saving its worth it in the long run

Re: Stopping down pipe rot!!
thing is, they rot from the inside too, filling with condensation whenever the bike is switched off .. i've removed what looked like a perfectly good OE exhaust before now and had it fall apart in my hands
