Does anyone know the size of the piping of a 98 3.0.......thanks

Hobo

good question, i'll guess 2 inches

klepto

either that or 2.25 Most people get 2.5" piping when they get an aftermarket exhaust

Hobo

although, its really the mandrel bends that lead to increases, but theres not much to be gained on our cars with exhaust, unless you have fi.

on the 2.3 at the resonator the diameter is about 1.25 inches... and 1.5 I believe throughout.... 3.0 probably 2.0 inches.

my tanabe is 2.25" full stainless. If i was to have a custom system bent up, it would with 2.5" tho

2.25 is all you need with the cl...

a 3 in diameter pipe can flow enough air for 900 hp... so unless you are making that much, its not only pointless but it will cause turbulence and the gasses will not exit as quickly, which is what were aiming for.
