Crap Coming Out Of My Exhaust

[dan.1337]

I've noticed that when i'm boosting above around 4000rpm, there's crap flying out of my exhaust. It kinda looks like a cloud of dust or something and it doesn't happen everytime i'm boosting.

My car doesn't have smoke on startup, or spit that crap out under about 4000rpm.

Can anyone enlighten me on what it could be and how i might be able to fix it?

Yeah you might want to look at a new engine, new turbo or the fuel your using...

Could also be need for a service, you havnt serviced it enough or just new oil.. could also be a seal but i doubt it as you would see smoke on start up ..

so you got abit to look at but hopefully its just oil hey

What colour is it? Most likely just excess fuel due to running rich on boost, plenty of Skylines do it.

running rich or ur blowing out the insides of your cat

i know i'm running waaaay too rich, so hopefully that's just the problem. it seems like it only does it once or twice after starting up before clearing up.

i'm in need of getting it serviced - so that could also contribute to it.

I was installing the numberplate on the rear of my car and looked in the exhaust and could see the insides of my canon were coming apart. I used a pair of pliers and pulled all this perforated metal out that was blocking the outlet. Then started the engine and gave it a few revs and all this fine dust came out in a big cloud. The canon is obviously rooted but its not noisy so meh
