I have a question about my exhausts. Will threading the 8 holes in my lid with nipples create any chimney like effect (if that exists), or is it exactly the same as just having the holes bare.
I'm debating whether I should thread the holes with a pipe plug to close it off, or just install the nipples and use caps for cutoff...
