Comments: I think it is a pretty good product, i think if your looking for that good loud deep sound this is the product. but it is not that loud where you can't stand it and it is easily drowned out by a little bit of low music in the cab, its pretty loud with the top off, i guess you can just hear it more, but ya, i like it a lot

Comments: I bought this after going to Big Dogs Offroad Main Jambo and hearing all of the other Jeeps that had them. Now that I have one I am liking the sound but I am thinking that I might have liked a Super 40 Series because I want it to be even louder. But the 40 Series is nice it has a nice throaty sound at 1000 and 2700 RPMs you know it is there at all the other RPMs but it is most noticible at 1000 and 2700.
