Ok there has been alot around this forum about exhaust which is better sounding and better as far as gains. I want to pick the best between Ultimate, RMR, Pruven and Buschur. A poll will not help me and neither will I'm just going to wait for such and such. I want to know why you would pick what you would. What has the most rice sound and what has the deepest. Also what will not lose the power right off the line like the the pruven system. If power is lose how much will a intake help? Thanks in advance. Trust me this is not the same as other threads.
