Description:

FS: New SMB 3.5" Downpipe with O2 Sensor Bung welded in.  It does require a larger midpipe which is why Im selling it.  The pictures should show the bolt hole spacing so you can determine if it will work for you.  Let me know if you have any questions.  I dont know if this adds much power over a regular 3" downpipe but if you dyno it back to back against one, i will send you $100.  Paypal or Postal Money order for payment
