2 questions here
1: What methof have people used to polish they're cross over pipes, had a look n the tutorials section but there's nothing
2: Does anyone run a different style of crossover? such as just a round bore? or is it easier/better to just go for the 2.2 set-up?
I'd still like to know how to get a good result from polishing it though, as the black stuff looks a bit of a bitch to remove
