My moto is too loud!!! These pipes were on the moto when I bought it. Can anyone tell me about the pipes, model, material, etc? More importantly, how can I tell if the silencers are in the mufflers, assuming it had any to begin with? My 2007 ADV had Lexx pipes, which I liked a lot. Not very loud, very little deceleration popping and most important and the reason I installed them, they ran much cooler than the stock pipes. These pipes make good power, plus I have great fuel economy, but they are too loud and have an excessive amount of deceleration popping. I assume the popping is due to insufficient back pressure. The PO said the moto was remapped for the pipes. The pipes, as seen in the photo, does have spark arrestors installed. Thanks!
