OK, so I convert my '06 BMW K1200LT to a Hannigan trike in June of 2012. Ace Trikes in NJ does a great job and it turns out beautiful as Hannigan makes a great looking conversion. It rides great, handles very well although it took a little getting used to the steering going from 2 wheels to 3, but no problem! Both my wife and I couldn't be happier. The only thing that doesn't set right with me is the dam exhaust note. It sounds like a bad exhaust leak running through a garbage can, especially under hard acceleration. The conversion calls for cutting the exhaust behind the Cat and extending it with flexible tubing. I've even tried header wrap as I thought it may be resonating within the extension piece. Has anyone else with this or any other conversion noticed a sound change or am I just noticing it more since the exhaust is enclosed by the body?
Secondly has anyone with the BMW Hannigan conversion found or installed a replacement system for this trike? There are a few companies that advertise systems for the 2 wheels version like Remus or RB racing although I haven’t seen any from the latter manufacturer.
