I've got Jardines on the 2005 I bought 6 weeks ago. I'n my opinion, way too loud. I've been trying to quiet it down, with marginal success.
I did my homework before buying it. This from the FAQs on Jardine's web site
Q:Is there anything that can be done to quiet them down if they are too loud?
A:Yes, we offer a variety of options to reduce sound on all systems. Ranging from quiet baffles to quiet inserts.
When I called Jardine I explained what I had, that I had read on their web site there were things that could be done, and asked what the options were. The guy on the phone was very rude, said "I don't know where you heard that", and basicly blew me off.
Maybe a touring system is different and can be adjusted. Apparently mine can't. Regardless of what their web site says, if it's not what you' re expecting, it might be too bad.
