I just bought some headers off of summit racing and I really don't know too much about cars at all. I have a 2000 Chevy Silverado with a 5.3 Engine. I was wondering if I needed to buy some reducers or anything else along with these. Here's a link to the headers I bought if that helps at all. Thanks.
