fitted my janspeed s/s rear box yesterday and de-cat pipe
but it rattles like hell, it seems to be the middle silence box, but it wasn't like this before, has taking the cat out, buggered that box, (too much pressure)
looks like i might have to get a stainless middle section made up with out that middle box
any thoughts welcome
anothing is , i have the oxygen sensor in my downpipe is this going to be affected in anyway since the cat has gone ?
no body have any thoughts on it then ?
