Dual glass packs...low rumble with lite foot. Neighbor annoying loud if I get on it. After I do a maintenance I will try to remember to do a camera sound video. Person I bought it from said the cat was stolen and the muffler shop suggested this as a temporary fix. And so it is still the same. Runs like a top. I really want to do a scan to see what error codes there are...and why it still runs SO WELL.
