downpipe install

  

1.8tterbo -> downpipe install (6/1/2007 10:11:56 AM)

I just bought a 2001 jetta wolfsburg and I want to put in a 2.5in downpipe that will go into a 2.5in exhuast im just wondering is there anything that i will have to re-program or change with the O2 sensors that will affect the performace and will it also help to get a coldair intake or will it make it run too rich and lose performance. any help i can get with this would be great.

it will help to uncork the intake side as well, but make sure you get a DP with o2 sensor bungs to save yourself the trouble at the exhaust shop, the ecu will adjust to the new part but you should reset the ecu to take full advantage...
