Thanks for your suggestions. I ended up leaving the Xpipe on. I was able to get the pipes in place correctly with a sleeve. I may go back to the cats, I have lost lots of low end power, but have more power in the higher RPM ranges.
One other thing I overlooked is that when I rebuilt the trans I changed the cluster gear ratio and first from 3.55 to 2.95. I've only had the car for a few months I haven't checked what ratio the rear is, but I know its not stock. Maybe lower gears in the rear will compensate for the gear change in the trans. The reason I changed the cluster and first gear was because first was to low and overall highspeed crusing was horrible, turning to many RPM at 70-80MPH.
Not sure what I'm going to do next-- Have stock TB and Intake, maybe I need more airflow?
thanks again
