Sounds good! Very Impressed that you snaked it by with the upper brace in place.
I recently completed my 4" exhaust build. I ended up using a bullet muffler before the axle in addition to a hooker max flow afterwards. The RH exit is definitely a more direct flow path, plus it probably doesn't heat the fuel tank as much.

ive been looking to dumb the sound of mine down a little. ive got the magnaflow race 4 inch on it now. I might do what you did .
mine does get the fuel tank warm.The stock steel sheild is long gone. I just saw a muffler heat shield that is held on with stainless straps. I wanna say it was DEI.

With mine going straight out my tank never got warm. It didnt cross over n come out the pass side. But if you got the say back half of the exhaust or just all of it black ceramic coated it would shed very little heat 👍.

I got to drop my tank soon again. I might use the one wrap in between the tank straps.
I like it going out the pass side like you did. id just have to tone the sound down. I like the sound, don't get me wrong ,but my car has been completely redone, and im struggling to hear for any problems on tset runs. and all I hear is drone. wont be such an issue once ive worked everything out and have more confidence in the car.
