No, does not need downpipe as the PZ header is a tuned-lengthed primary all the way to the collector, then bullet, proceeding to the piping. No other additional costs here.Originally posted by InitialD@Feb 15 2005, 11:15
Would I need a new downpipe? Does the RM450 include the downpipe?

The Powerzone extractor for Kelisa is a 3-2+1 design known as a tri-y.
The O2 sensor wire has to be extended.
et5828: We don't know why yours is not, as you said it's ori. Is it Powerzone extractor that you have? If so, please come in we'd like to see why your exhaust is not performing. After the extractor what piping and silencer do you have?
