So i finished putting in my s2 IM and it was all good, untill i put in my greddy header it sounded like i had an exhaust leak were it connects to the cat, but i checked it twise and no leak, but it also started to rattle in first gear i sounded like a ricer, so i took it to a muffler shop to check for leaks and he said it didnt have any, he even lifted the car and reved it an he said it was all good. So should i be hearing this noise, is it normal, does it go away? ill try and get a video clip, but over all the car runs about normal no loss of power just an anoying sound

i belive it could be the exhuast gasket not fitting right or just not super thick header, my obx has that type of sound.

sounds like your average honda to me..

 

well after watching the video myself again, yeah i really didnt do such a good job showing what im talking about, it sounds like im hitting the heat shield but im not, i hear it when i drive next to a curb a loud *** hizzing sound, i did use my oem doughnut gasket i might just buy a new one and put on my test pipe maybe its the cat making the noise.

 

sounds like its hitting on something.
