Default Pre cats gone---------------

Just had the pre cats on my 91 removed and replaced with new pipe----------what a difference in sound and in the seat of your pants.
cats had 163000 on them and took some talking to have the shop remove them---the only way they did it, was to put a new
3" inlet /outlet hi flow cat in as the main. do you think the car will have to retrain itself??? i did not get a chance to open it up as we
had a big storm here in n.j. and it rained so hard you could not see-------------JIMBO :D :D :jester
