Exhaust Flange

[likibow]

hey guys i have to change my exhaust flange but i don't know the pipe diameter of the ST 4.6 the kit goes from 2" to 2.5" anybody had done this job before? thanks

which one, a flange between a manifold and y pipe, or at the exit of the y pipe? the end of the y pipe is probably larger than 2.5, but smaller than 3"... may need to skip a bolt on fix and break out the welder...

06bluez the end of the y pipe i bought a caliper and measured it 69mm 2.71 inches abd all i've found is for 2.5" pipes so as you said break out the welde, thanks!
