Dear Sifus,

Please give me your advice on the situation below:-

I'm driving a Wira SE 2005 original settings. Recently, my muffler has eroded and when I sent it for inspection, they tell me that even my mid-box/silencer needs to be replaced. (I also got a 2nd opinion to verify this)

My main priority/intention is to upgrade the exhaust system to maximise my engine’s potential legally. Also, I’ve always been fascinated by cars with 2 mufflers and was wondering if it’s possible without...
