Some sort of burn smell when RPM goes high

Hey, guys.
This issue has been happening for sometime, but since I never really cared for it, but I thought I'd still ask. I searched for the answer, but it seems like I'm the only one?
So I bought my car new from dealer which had like 150 miles when I bought it.
This is my DD and I don't track the car and everything's stock, except for the exhaust. Mine now has 39k miles and I rev to 8kRPM time to time when merging onto a freeway from a ramp usually in 3rd gear. When I do bring up the RPM, I smell something burning. It goes away tho.. So when the motor is pushed "hard", I can smell this..
Has anyone experience this? My car does burn oil. I need to top it every 5k miles or so..
Future mod consideration: exhaust, pulley
otherwise, very happy with how the m3 was born

I notice when parking in the garage if i've given it a bit on the way home late at night. I'm not sure its a problem - I just think its the combo of brake smell, tyre smell, engine heat etc etc from giving it a hiding. If you have ever smelt a race car (like a Nascar or an OZ V8 Supercar at a pit stop or after a race it's a similar but more diluted smell. Might just show that you have been exercising it appropriately.

Unless you have a particular problem I don't think it's a bug - it's a feature.
