I have a BP 347 with FF ball flange headers, i'm fitting GAS-N standard side pipes. I know the template FF supplies is undersized and just a guide but it seems like the location they suggest for the cutout is a further forward than the header output if it was to be pointing straight, even allowing for clearance. It's the same on both sides and I know the body and engine are aligned. It's not hard to make the cutout further back I was just wondering if anyone else found this and if their answer was to adjust the cutout further back.
