When i bought my bike it only had a open 4 into 1, and I have been looking at exhausts. I like the reverse cone, and i see that most of them look basically the same. I initially was going to go with the DCC reverse cone, then i seen the cone engineering one, which basically looks identical. And so does the lossa one too. Are they all basically the same? Any of them sound different from one another? Anyone point me to a sound clip?
