I read on another forum, possibly all par? That Chrysler did extensive research & tuning on this exhaust system and gained 30 or 40 ft. lbs. of torque with it. I just used the spacers on mine. Ducati, for one & Husquvarna have used the loops for performance tuning over the years with good results.

Very interesting stuff, sucks that it was engineered to have that loop :(

For all the afore mentioned reasons I would NOT touch that exhaust loop.
Rest assured that the engineers with all their might didn't just "decide" to slap a loop on.

I installed my 2.5 inch AEV Dualsport suspension kit without any modification.

I am trying to picture where you all are talking about. Is it before the cat or after it?

Drivers side right ahead of the crossover pipe 2012 model.

So you are talking after the catalytic converter

Yes right after the cat before the y

I have a 2012 I installed the mbrp cat back exhaust. I believe I did lose some mileage but I did not notice any power or torque loss.

Does the mbrp delete the crossover?

Honestly didn't really think about it when I was installing it.
