Ok let me put this a different way.
I first deleted my stock muffler and DPF leaving only the stock cat, no drone.
Then when I deleted my cat for a not so quiet DE quiet tone front pipe I had mucho drone and stinky exhaust.
Being desperate I installed the 14” Magnaflow muffler where I mentioned and even added a 4” Magnaflow flowing cat in the DE quiet tone which didn’t help.
When I decided to try the 17” FTE the only open space I had was where I had already mentioned.
PER FTE, not my decision THEY TOLD ME IT WORKS BEST CLOSER TO THE ENGINE.
FTE actually suggested that I put it in the DE front pipe, this I did not want to do, the FTE will not help with stinky exhaust fumes.
All I was mentioning was what FTE told me.
Not a debate on where it works best, put it where ever you want, but I’m pretty sure FTE actually knows best.
Below is my DE Quiet Tone pipes, one with cat one without, both retired.
