Sooty exhaust

[rlees85]

Hi All,

Sure its nothing serious, its more of a question of curiosity.

I had the best part of a janspeed full exhaust system for over a year. Never had soot collect around the exhaust tip.

But now!

I had a stainless steel secondary de-cat pipe fitted, making the whole exhaust janspeed. Now after just a few days the exhaust tip is blacker than the ace of spades.

Does this mean its running rich, burning oil, or what used to be collecting in my home-made de-cat (hollowed cat) is now just collecting at the tip and is perfectly normal?

lol cheers

Perfectly normally i would have thought.. mines covered in it.

Probably running slightly rich now it's better flowing but you have this on all non cat cars so I wouldn't worry

im actually glad its running slightly richer.. its been running lean for ages and it explains the extra ponys ive been noticing.
