Just wondering what the dia is of the muffler on the Ram 3rd Gen Hemis, and the resonator size?

I think that mine is 2.25 or 2.50 dia.

The reason I ask is: I have a 07 Dakota with the 4.7 HO engine. I had the pipes just after the cats changed to 2.25" instead of the factory 2", then Flowmaster Y collector into single 3", then had a Hooker Aero Chamber put on, no resonator. Resonates like hell at 1800 rpm! I dont wanna try muffler after muffler, or a bunch of "resonators". I know a factory muffler might not sound as good as alot of mufflers out there, but I can bet it won't resonate like this one. And, I was hoping they had something as big as 3"?? I know I can get a used one cheap, just gotta know what model to get. Thanks

The HEMI trucks use a 3" inlet muffler. I don't know if the tailpipe is a 3" or 2.5"?

Starting in 06 they are 3" all they way through past the ypipe.
before that might be 2 3/4 or so past the y.

thanks, I bet I can make the whole muffler & resonator work, without cutting out any of the factory good bends, just a matter of shortening, and trimming
