I understand completely, when I searched for rims I had the same feeling and dodged a couple bullets. I actually unbolted everything on my exhaust, no cutting and no welding so I could do something else if I didn't like it. It's all clamped up nice and tight. Only spend $30 on my thrush welded muffler and any other money I spent I can use on the next muffler setup if I don't like this one in the end.

 

My truck is a cat back magnaflow exhaust setup. I kept the stock end and it put a nice tip on it (zip screw ftw) the drone goes away. Trust me I don't really notice it anymore and I don't get complaints. Just get used to it is all.
