Benefit you? Not much if any.Especially if you are keeping the stock catback. All I know is people with the S&S headers have ran 12.19 in the 1/4. that was with a 2.8 pulley. So they are definetly capable of that. And if that's all you want then why not get a cheaper set of headers that seal great and have no othe issues. Wrap them. And be done.


And no, none of the intake kit's on the site have a filter with them. But any filter with a 4'' inlet will work fine.
