can you not just get a tip welded on instead of changing the whole backbox? Petrol box will be well restrictive

As already said, petrol boxes are hugely restrictive as a petrol engine requires a certain amount of back pressure while a turbo diesel does not.
if you lie the oem look of the box though you could cut the top off, clear everything out of it then weld the top back on for a hollow box. would be more mot friendly and sound alot better

Does anyone know the diameter of the exhaust. I can't get my back box off to measure it so I measures the circumstance which was 16.5cm and divided with the pie thing and got 5.25cm-2.06". Does 2" sound right for the standard pipe.
