<![CDATA[Exhaust Silencer question]]>On the stock exhaust setup, you have the Cat, then a Silencer, then a Back box. Do you need that center silencer for an MOT? I may see if can come out and some normal piping welded in place? Any advice on that front?

It can also be quite a harsh sound too.

I'd recommend puting a straight through mid section silencer in which has almost identical flow as a straight through pipe, but will take the raspy edge off the exhaust note.

All depends on how well you get on with your neighbours :oops: :imout:
