I upgraded from my old Conley 3" dual system to the RJC Cross Flow system. What an improvement! Kudos to Jason for another stellar product. The drone I had in the old system is gone. My wife is sensitive to drone and she gave it her stamp of approval. Now she'll actually go places in it with me. lol! It's not as loud as the old system and I'm okay with that. It's nice to actually hear the radio when we're going down the road. The sound reminds me of the stock sound but louder and better of course. It took about two hours to remove the old system and put this one on. I used band clamps instead of the included clamps. I think the hardest part for me was the back two hanger bolts that go through the frame. The passenger side was easy enough but the drivers side took me a little while to get it started. Aside from that it all went together nicely and I have plenty of clearance with the rear axle and gas tank. All in all we are very happy with it and I would recommend it to anyone on the fence about a new system.
