Hey Henry - I also replaced the exhaust on my 02 Av. It's louder than stock for sure, but not the drone or what I would call loud (if I want loud I have a drag car for that). I also had it rerouted to be tucked up higher between the frame rails and exit as just a slight turn down ahead of the rear wheel so it won't get inadvertently crushed by anything. It's also higher up so less likely to suck in water.
Is that an awning in your pic? I've been considering getting one. Which one did you get and how does it fit on the Av? Thanks.
