as per title my h-pipe for sale... came with the car no idea on what it is.. seems to be made in j-land because of the cannons attached to them jasma. so i can only assume.. quick info on the car it came off, 130,000 on clock (we know jap cars...) but it was imported early between 2001-2003 forgot but will check, its a 2 seater if that makes any difference. the resonators/cats/etc (not good with this stuff) has stamped on them WALKER GA11680, googled walker and apparently their a big company over in the US.. but ive never heard of them before.. chasing $100 for it.. also can anyone clarify if they are resonators or cats?
