Started this evening with a cold chisel and drill to break up and remove the cat on a 2010 GSA
Long slow process but making headway but now need a longer drill
can anyone confirm whether there is a back plate before the cat in the headers or will I eventually breakthrough
dont ask why i am doing this,
