exaust

  1. Problems & Troubleshooting
    Hey guys! I'm pretty sure I have a bad Catalytic Converter because my check engine light is on and my obdII says I have an exaust leak. It also smells bad when I floor it. Should I just ditch the cat and clear the codes for inspections or get a high flow cat. The cheapest option is prefered...
  2. General Discussion
    I just ordered a new zzp downpipe with cat 3". However the stock exaust is 2.5". will the back end of the pipe connect to the remaining exaust pipe ok, or did I order the wrong size without upgrading more? I saw some people recommended the 3" but I'm still not sure how it will fit :huh:
