Sold the only pair they had at the show you say....YUP, that'd be because I bought them
I agree with you on two things:
1: Yes, they are REALLY loud, louder than I had wanted...but you get used to it.
2: They do look the dogs danglies.
I had mine on in about 30 mins. I took the pannier sides off first. Had a bit of a juggle to get what side went where etc. but all on and no leaks. 1500 miles later, better midrange, better low end - not so much chugging, and about 4mph off the top end...indicated 132ish vs previous indicated 136ish. Remind me to remove the secondary butterflies next time I have the tank off...
