Excellent. I'm now hopeful.
Outside of the rattle can you guys chime in on what the drone is like? on your highway drives? :
I've yet to hear it but I don't always drive with the flaps open. So far so good on that front. I'm hoping the new MPE will be drone free as well.

Mine (1st design) was tig welded all the way around. It's as stiff as a board and appears to be one solid pipe from front to back. No rattles. Drone is the same as it was with my resonator delete dinan pipe & stock muffler.

A little update...

The problem was a wiring issue apparently. They replaced the faulty wiring. Easy fix... and euh...
I think the MPE was broken from the start No wonder I was quite underwhelmed by it!

The sound is completely transformed. A-MA-ZING !
No more rattles when cold start, the drone is still present but I don't care, it's different.
The sound is so much more warm, present, loud, rumbling, alive, head-turning...

I'm in love again

^ glad to hear. We have a new MPE on order. I hope this rattle goes away. Thanks for the update. I'll be sure to post my update as well.
