Next part is up for debate
Left cats exhaust is all stock just replaced muffler. It also seems to be getting louder. Has real deep throaty sound when driving normal
I installed the 18" case magnaflow and have LT with a highflow cat and sounds awesome. Way better then the flowmaster I had. Its not stock sound when cruising but sounds really good. At WOT or under load it sounds amazing

I think it will be too loud but that's just me go with a bigger body.
Ordered up me a 4" in/out spintech outlaw muffler yesterday. Prepping from my LTs
This is the 14" long 4" round Magnaflow I had before
