Quick question for everyone... I'm taking the stupid fart can off my 97 GS and replacing with the stock exhaust. I live in MA and FL and stuff rusts QUICK. Would there be any reason why painting my new muffler with clear high temp paint would cause me problems? Would it actually protect against rust? I'm not doing this for looks, only for function. Please educate me. Thanks! :thumb:
 
There is no point in painting your exhaust to reduce the effects of rust. If you're that worried about rust it's time to invest in stainless steel exhaust.
 
Exhaust systems are pretty much built to deal with rust. Painting one will make it stink like you won't believe. If it's aluminized, it'll only hold up for about a decade. And if you've not gotten a new car by then, it's time for a life inventory.
 
Paint it with one of POR-15's products. AMAZING stuff, really. Been using it in automotive and marine restorations for years. Check it out. www.por15.com
 
You can only paint the outside of it, correct me if I am wrong but exhausts usually rust from the inside out because of condensation in the pipe. Salty air + condensation = rust

you can try drilling a couple of small holes like they did on chargers and challengers back in the 60's to give the condensation somewhere to escape out, but I would not worry about it.
When it rusts just go get another exhaust system made for 100 bucks
