I think I am going to do the stock exhaust modification, but I'm a bit confused after looking in my tail pipe... (Insert joke here).
I don't appear to have any sort of hole in my stock baffle, I am looking at the stock baffle right?
These pics are of the top and bottom chamber of the stock exhaust. Is the bit I'm meant to drill the solid metal part in the middle?
And to mod I basically stick a 3/4 drill bit in and go for it?
