standard na and turbo exhaust diamiter sizes

[Guest Enzo]

i need to know the standard exhaust bore for the na and turbo,

does anyone know off the top of thier head???

[Mikey Jay]

Do you mean the exhaust tip, or the piping before the backbox?

As can measure my exhaust tip at the end o work if you want?

[Guest Enzo]

thanx for your help mj but imactualy after the diamiter of the piping before the back box, i think its 1.75 inches for the na and 2" for the turbo but i need confirmation of this

I would agree with you Geo on those standard bore sizes.

1.75 for n/a

2" for turbo

I've upgraded to 2"on my beast and the next standard size down is 1.75" so the n/a has to be that.

Turbo people usually upgrade to 2.25" or 2.5" so I reckon it safe to say oem size is 2" .
