I want to start by saying I've been a member on this site for nearly two years but this is my first post. I also want to say thanks to all of you who post your valuable knowledge and experiences with these cars, for this website has helped me tremendously with my car the past few years!


Anyway, I bought and installed Robs catless, cutout downpipes a few weeks back on my 2005 graphite SRT6. I like the way it sounds inside and out, but I want more (you all know how that goes ) I picked up the Megan Racing MR-S muffler off Amazon because of all the praise it seems to get by some of the members on this site, and I really enjoy the way it sounds based off YouTube videos.


Keeping my stock resonator in place, my question is, would pairing the Megan Racing muffler with the downpipes be a good idea, or am I being completely ignorant? Would it be entirely too loud? Could there be backpressure issues or potential harm to my engine by doing this? Does anybody have any experience with this?


Much thanks
