Mini Review:
For anyone wondering what the sound difference is after adding a dual resonated front pipe to your exhaust setup: the answer is.. not much lol. Slightly deeper, slightly more rumble (not comparable to swapping for an UEL header), and subjectively about 20% louder. Otherwise, the sound is very similar to how it was with just the catback and hard to tell on video unless you're listening critically with headphones. Overall, I do like this mod and my quest to shape the ideal daily driver friendly exhaust sound is complete. Just keep in mind that the change to sound is small if you're thinking about this mod too.

Additional remarks:
No noticeable difference in performance
Slight improvement to in-cabin drone
Exhaust fumes can be smelled when accelerating hard but not when driving normally
No check engine light or fitment problems
Pops on rev-matched downshifts are more pronounced and frequent
