Protection Against Exhaust Fumes

[ClutchBurndout-:(]

hey all, like a lot of others, im getting yellow on the back of my car, its easy enough to get off, but will it eventualy stain the back end with yellow? Or will it always just be on the surface and be cleanable. I need to know so I can decide weather to put my stock cat in or not. tyty

I'd run a cat if I were you, especially if your staining your rear bar. Any cop that knows his shit will recognise the yellow stain then you'll be up for a very large fine.

Cop see's the yellow stain.. his gonna' leave a stain on the back of your trousers lols.

and a yellow sticker on your windscreen.

But i havent tried removing it off my mates car, he got sick of it and put the cat back on and got a new rear bar

the fine for no cat won't be immediate, it involves being defected first. Then the EPA will need to conduct an emissions test, which is long and expensive, so im sure before you get officially fined for having no cat, you will have put a stock one on.

would not run a modded car without a cat. not only does it give the yellow stain off to attract cops all the cop has to do is smell the ex gas and he will know u dont have a cat. its a completley different smell of unburnt fuel and un converted gases. smells like my R31 race engine. has no cat. u can get rid of the yellow stain by running c16 or something but i dont think having no cat is worth ten bucks a litre haha

if you give you car a good wax first then after that atlease give it a wash everyweek it will come of very easy. i get the same on my 34 and after every wash i hit the whole rear bar with quick detailer spray and just wipe it off. good as new.

if you do that weekly your car will be clean and the yellow patch wont be noticable

I run a cat, brand new one actually, and still get the yellow stain...

Exactly!

get some high quality "Paint Cleaner" not some abraisive crap that strips your paint, and give it a good clean. Should remove the stain. Then give it a good polish and seal with either a wax or a polymer sealer. This should then protect the paint from further staining.

ive also heard that the stain can be from the exhaust itself being too short. if u put some spacers in it and make it stick out a bit further then it shouldnt be a problem. all fumes are comin out further from car.
