I will come out and say it, but I'm pretty cheap. Mainly due to having 4 babies and a wife. So when I look at motorcycle parts. I may tend to go as cheap as possible. Looking at these fake toce exhausts looks like its just a straight pipe. I would guess this would not help with any back pressure. If I dropped in the DB killer would this help with that? Also, will this hurt the bike in anyway? I would not think so but if there is something I am not thinking about would appreciate any info. Thank you all..
