Hey, don't flame, but is this any good ? ( 3" stainless flex.) Will it breathe ? Will it hold up ? Anybody ever tried any of this ?

the ribs in it will cause hot spots and turbulence. i wouldnt recomend it

Wouldn't the fact that it's 3" instead of 2 1/2" offset any "drag" from the not-smooth inner walls ?

Exhaust velocity will slow a bit in the larger diameter of the flex section.
