I have been running a cobbled together OEM 3" system for almost 9 years now. My truck is only slight turned up and I have had no issues with the 3" system....BUT when I do replace it I will be going with the 4" system with a flow through muffler. Straight pipe is fun for a few months then the drone just started to wear on me....couldn't be happier with the flow through muffler added to keep things a tad quieter.
So if I were you I would do the 4" with a muffler and call it done. the cost saving between the 3" vs 4" is negligible and the 4" is pretty much the go to replacement for everyone.....not a bragging rights thing. Plus the 4" system will give you room to grow down the road if you do change your mind about how much power you want.
