As the subject states... anybody know what the piping diameter is on the TRD exhaust?

BUMP

Nobody has any information???

it is 2.5 and the pipe leading up to it with the scuba tank is 1.75 so get it replaced from the s pipe to the muffler your good you will notice the difference

im pretty sure the trd exhaust is not 2.5 ..i believe it's 2 1/4

it is i mesured it from the axle back it is now mine is 2.5 from the header back

So we're sure it's 2.5"?? I thought it was 2.25" as well.

2.5
