In regards to the exhaust outlet size - you cannot go "too large" after the exhaust merger. That means you could have (space permitting) gone with 5" exhaust if you wanted to, and would have lost ZERO power. On the flip side, with exhaust piping too small, you run the risk of actually not gaining as much power as you otherwise could have due to added back pressure.
That's not to say this is a bad exhaust or you shouldn't (or aren't) happy with it, it's just some of the things you did aren't what I would have recommended if you had spoken to me.
Otherwise, I'm just here to see where this build goes, so carry on.

The main reason for me to delete the old oem exhaust box muffler and pipes was to drop weight and delete the secondary cats. I know that an exhaust does not net much extra power on its own anyways. There is no replacement for lightweight.

Thank you thank you! I have DIY done everything myself since I learned how to wrench when I was 16, except for a few exceptions of alignments and smog testing as I dont have the equipment or tools for that haha.

Thank you I love my Wedssport too! Yes shedding weight off the car without stripping the interior/exterior is ideal! No replacement for lightweight!
