5'' muffler question
 

I have a 2005 dodge with a 5'' exhuast system. I bought that way and i think it comes with a resonator, but it is very loud and annoying in the cab. I was wondering if like a mbrp muffler or something should do the trick or what do you guys recommend. I would like to just take the resonator that is in it out and just go with the muffler, but i'm not for sure yet.
Thanks
