Hi folks, I am looking for a used or new Supertrapp muffler (that I can adjust with discs). And who is the vendor I can talk with? I have a 2 into one header (Jardine?). I ran the bike in the FCB350 with USCRA. I know the exhaust is not really working like it could. My friend Killer Baker said it was my body weight and talent that are holding me back. But I think if I was running his homemade (weird and questionably loud) exhaust, I could do much better, maybe beat him on his old age. But he won't share any secrets, legal or not. So which Supertrapp would be best on a 2 into 1 header for stock CB350? I don't want to spend more on the pipes than I spent on the bike. FFS. Thanks!
