I have a brand new 2001 F-150 XLT, 4.6 Liter Automatic. I went to my local muffler shop and told them I wanted to get a price on a Flowmaster muffler with dual pipes and 6 inch Chrome Tips. They gave me a great price, but I want to make sure that this will not void my warrenty, since my truck is only 1 month old. Thanks any help is wanted!

It will not void your warranty. Everything behind the cats back is ok; the cats are a 50 State Federal Law.
