No issues with the fumes or anything like that. Was stuck in traffic right after I put it on and didn't notice anything at all. The sound was ok, just wasn't for me (see below).I may be interested. How did you like it? Any issues with fumes in the cab with top down since it dumps under the Jeep, if you even know? How loud was it compared to stock? Why did you buy it then the next decide to sell you Jeep the next day. Just courious.
