Here we go again.........
Yes mounting the muff forward will kill the drone. I had the Jardines on my heavy truck and added the resonator to kill the drone. Hated the sound, or lack thereof, so I got a Allied muffler from Rip and mounted it forward. No drone and truck sounds like a beast now.
On the 02 I mounted it forward right off the bat and no drone.
I had welded joints too. I just had Rip make me a straight piece with a flared end and cut into the system. Seeing the muff has two female ends it all just slid back together.
