How much you got to spend? Lol...
You going to show (stainless) or race (anything will do)?
Are you planning future mods and what's your plan? I went against the grain and spent a little more on the ceramic Pacesetters and couldn't be happier. Sure... SD's ... Everybody's got them, what the hell. It just all depends what you want.
Do research, set short term and long term goals and consider where best to spend $. Headers are all pretty much the same, with some minor exceptions. Read the link, read all tHe opinions, ask questions, when you're sure what you want, read and ask again...
Then go for it...
...oh, by the way, recently changed my cat-back (to 3") and liking it!!!
