Does anyone have any expierience with the rusty's exhaust system for the JK. I am thinking about ordering it instead of having a new muffler welded in since the cost is pretty similar.

 

I didn't go with the Rusty's exhaust for the JK, but was drawn to it for the price. My concern is that is using a cherry bomb muffler and I was concerned that it would be too damn loud. I ended up going with a Magnaflow stainless muffler with stainless tip for $186 out the door and probably lost 20 pounds off the rear of the vehicle by removing the stock muffler. I was having the same problem you are, which is that there is very little info out there on the Rusty's exhaust and found that most that weren't doing catbacks, were doing flowmaster and magnaflows. Sorry that I couldn't be more helpful and good luck.

 

Its not too loud. I like it. Its a good buy.
