hey, im selling a somewhat used APS Test Pipes for 350z! I had it on the car for a week but decided to go with the Ultimate Racing High Flow Cats instead. The APS sounds awesome on the car but i dont want to go to the hassle of taking the test pipes off when i go to car inspection. The Ultimate Cats meet or exceed all 50 state emissions requirements! I bought the test pipes for $220 shipped and im only asking $180 shipped! Pm me if interested, thanks!!
