Hi all,
I have a 2010 Ram 1500 sport and I was wondering what is the stock chrome clad wheel specs, I belive they're 20X9 but what is the backspace and bolt pattern size? Also I wanted to know what is the stock muffler size inlet and outlet. I heard it is 3" inlet and 2.5" outlet but I'm not sure. The reason why I'm trying to find this out is because I want to change to an aftermarket wheels and muffler, but I want to stay as close to the stock sizes as possible. Any help would be appreciated.

 

I would like to find this out myself. Also, I don't know if this would be helpful to you as well, but I have been looking at flowmaster mufflers and there are a few options. I've got a single in/single out exhaust......from flowmaster you can either get center in/center out, center in/offset out, offset in/opposite side offset out, and offest in/center out. I am not sure which one the 4th gen ram requires.

I could climb under and look but as you know Canada is still a little messy with snow and rain still!
