https://www.amazon.ca/Vibrant-Performance-10633-Muffler/dp/B00LF4VV80 is better sized for us running the flat six. Two 2.25" in one 2.5" out with the same body size. The extra 1.5" space not running a v8 and a bit more angle should help with fitment. Twice the price of the magnaflow dual/dual I thought I would eventually buy for the crossover, but less fabrication after for the tailpipe.
From the limited reviews I've found they seem to be quality mufflers.

Fitment does look tight, has the car been on the road? Any contact between the muffler and the bumper cover when things start moving around. Are you worried about heat transfer to the transmission the way you have it mounted or melting the bumper cover?
