Im workin with a 94 Z28 has a LT1 that is stock for the moment but wont stay that way for long. I know im going to need to upgrade the exhaust along the way of headers, of which ill be buying longtubes soon along with some electronic cutouts. What I dont know is what is good to run from the headers on back, or what I can actually run for that matter. X-Pipe, Cat Back, etc.....and also if ill be needing subframe connectors to allow all of this to work. Any help is much appreciated.
