After x pipe....

Yes a street Dart. It does sound nasty. Had duel before, just added the X pipe to get a smoother sounding idle. park 1200 RPM, Goes down to 1000 in drive. I am calling him Monday morning. It is a quick little Dart!

Yeah the 200 rpm drop is what's causing the hard engagement. It's the load on the driveline that is doing that. So it idled at 1200 in and out of gear before that?
