Just got my Pumkin back from the mechanic.
2 new front brake calipers and a de-Cat pipe installed.

I am really impressed with the difference, she seems to rev quicker and smoother.
However I am noticing a little more smoke when she revs.
By no means is it a ****load but it is noticable.

Is this normal?

BTW, it sounds soooo much nicer.
More whistle and gurgle from the turbo, like a tractor.
I think next I will pull the mufflers off.

I assume its normal. when I fitted one to mine, i noticed the same thing. But it's all good runs smoother (and louder)

Mine did the same.
Cleared after a bit.
I think its all the **** thats built up over time, getting blasted out.
