Hey guys so I just removed my cat back today I love the way it sounds but I'm kinda iffy on some stuff. The piping that was left exposed I went ahead and tied it down with the sway bar so the pipes won't rattle while I drive. But than I noticed that having the pipes tied makes them point up toward my gas tank. This makes my rear bumper heat up while the cars on and not moving. Could this much heat affect anything. If I dont have the rear pipes tied down they rattle while I drive when I reach about 3k rpm.
