I'm thinking of deleting my catalytic converter. If I do will this cause problems. I'm getting ready to do exhaust work, while I'm at it I was going to yank the cat out. If it will be a problem I'll just leave it. But I would like to open the exhaust and let the motor breath. There is a ram air pipe in mind as well. As far as I know no one makes a cold air intake for a mk1. Will I be running into problems with any of these plans? Any info will help. Thanks.
