Unless you plan on putting out some massive hp numbers anytime soon, forget the headers.
The stockers flow just fine for most applications, and changing them out is a royal pain.
In my opinion, flowmasters are too loud. Look for the MAC or Dynomax cat backs...
As far as the X-pipe is concerned, go with the Bassani X.... accept no substitute...
