2" too big ! UGPM, thanks

Thanks for ur reply.

So, which one will have better petrol consumption and performance; 2 inch or 1.6 inch?

I have found my Original 1.6 inch Centre Piping almost "KO"; intend to replace it soon. Quoted by someone said that 2 inch have better petrol consumption & better performance. It's true?

My Target: Better Petrol Consumption, Better Performance and Silent Exhaust (Twin Cap Type)

Part to be change (Proposed): Exhaust Converter/Filter (original size), Slightly bigger size of centre piping (maybe), Rear Exhaust (twin Cap type)

Could you quote the best best for the same on Proton Wira (Auto).

TQ

Any recommendation for KIA Picanto (1st Generation)? (Breakage/cracked at centre of the pipe already) How much? TQ.
