Okay, this is my first time running a speedbump at 30-40 mph. it wasn't just a short speedbump. it was those tall and LONG speedbump. i did not noticed it. no signs nor light under it. just hex mark which was not noticable. but yeah, i post this thread here because i need you guys help. after i flew from the speedbump, my exhaust pipe or something is open. now it's making a loud noise like a fart can. either it's the exhaust pipe or the header is loose. i need some quick info of how you guys install the header OR the exhaust.
