I am looking to buy a 4.8is in the near future. Been looking around at 2004-2006 models. The one thing I don't like about the truck is the exhaust tips. Yet, everyone on the board seems to love them. I prefer dual round tips. I see several people switch to the 4.8is style tips. I assume I could remove the tips and put on dual round tips to fit the 4.8is exhaust?
