ok so i went and got my whole ehaust done there a couple of weeks ago.....obx 4-2-1 header with downpipe, going into a round 4x4 flex(i think) magnaflo cat, 18 inch res, magnaflo street series mufflers with 2 1/4 piping, fine and dandy. I was going to use the spring kit that came with the header but i thought it would be much better to use a flex. So when i back up it sometimes makes a small knckoing noise like a lil rock hit the car or something. Would that be the flex moving or could it be the wrong flex pipe? Also i dont know if they welded where the header attatches the the down pipe, so if it isnt could that be making the noise too?...and i dont know why they wouldnt weld it cuz i never got the spring kit put on it.....
