Nothing against you, I found this on the MangaFlow website..
"To reduce additional backpressure, the OEM exhaust tubing can be replaced with madrel-bent tubing of the same size or one size up from the OEM. As a general rule, you can enlarge the pipe diameter of your OEM exhaust system by 1/4- to 1/2-inch to increase your horsepower. However, any additional increase in pipe diameter is likely to decrease your performance; specifically, low end torque.
Bigger is not always better."
On a cat-back, a bit bigger won't hurt AS bad.. But the primaries on an exhaust manifold are just a little more important.
Just my 2˘

I am reusing my stock gasket and have no leaks with it so I'll just stick with this until it starts leaking. I'll probably end up rebuilding my engine or just sending it into jbody so the vibrant will eventually be fine for my engine.
