not too much. the exhaust gas expands as it cools down so the 1/2 inch difference exiting the turbine is nominal. id say to go full 3 inch after the flex section.

Cause the 2.5 is easeier and cheaper to make !!l ol So no big differece with it 2.5 instead of 3??
ANd with the rest 3 " what hp would u gain do u think??
