Hi sifus,

Just wondering what is the suitable exhaust piping & muffler size for BT 5 speed?

2.3" or 2.5"?

And also S flow better or straight flow better?

2.3 inch is the best for bt or svt...muffle inlet 2.3 outlet 2.3 lagi bagus for straight flow...but most important is the bending of the exhaust pipe must be mandrel bend...dun use those normal bend which the pipe get smaller diameter at the bending place.

Oh. So its straight piping is more suitable for BT.

Btw, when u say 2.3" piping is the best size, is it better to do 2.5"? As when we do 2.3" the actual inside is smaller 2.3" only. Or we shall tell the person who do the piping that we want inside is 2.3"? Right?
