Yeah. I have sanded the cylinder top a bit, that would def. help.
Guys, I'm having problems with fitting the pipe. I have two options. I can either put it to the left, or the right. If I do put it on the right, it will be easier to place, but will have an extra 3-4cm header. Is that fine? I know it shouldn't have very sharp curves, thats why I was trying not to put it to the left.
