Excessive exhaust fumes at high revs

[lucy88]

Basically, whenever the revs hit about 5k, a lot of white smoke comes out my exhaust. It is made worse when driving fast (>100mph), and the smoke condenses into water on my back windscreen. I used to have my cat in and this made it worse. Decat made it better but its still quite bad.

I know without having a look at the exhaust its hard to say whats causing this but any ideas from past experience?

Do you do alot of short runs? Could be water just chillin' in your system?

If there's that much and it's really white (not condensation) then it could be something else i guess!

White is water.

Standard exhaust ? I'd bet my left arm that the boxes are just full of water.

Smoke doesn't condense on the window BTW

It's steam from water that collects in your exhaust. Nowt to worry about.

well i do a mixture of runs, but driving to work and back is about 10 mile trip so not short no.

Yeah its a standard exhaust with decat in.

How can i stop the water collecting in my exhaust?

Would the same happen with a RS192 exhaust?

Probably less in the RS192, the standard exhaust is pants in just about every aspect

 

[TheEvilGiraffe]

10 miles is short...

Yes, it's a by-product of petrol and air being exploded

Just dont worry about it.

mate I get exactly the same in my 182, when you give it some it makes the rear window wet, its just water, nothing to worth about.

Mine did it the other day, I got abit happy with the jet wash and some water got in my exhaust :clown:
