All the pipes (Vipers, Viper-2, Reapers, and Mayhems) we make have a support brackets. If you don't have some sort of bracket supporting the exhaust they will crack or damage the exhaust ports.I purchased the viper2 pipes from Fuggin and it looks like the support is removed. i am basing this on the picture of Preditors bike. I have the same model and i am goint for the same look. It looks like the exhaust support is removed. I could be wrong... Any help would be great. Thanks
