I've got DC's intake, added about 20 rwhp. Arrow was the first and Dan and Lyle told me that they improved on Arrow's design. At around $1200 good value. Either one will work great and expect 16-24 rwhp since you already have headers (Don't get hung up on the dyno comparisions here, too many variables). Never heard anyone having an issue with a ported intake. I've also got ported heads, gave me about 22 rwhp, not a great cost/value compared to the intake or headers. If your looking for max hp at the track, run 95 octane with the mopar ecu and consider a catch can. You'll be surprised when you pull the intake, lot's of oil is in there. Good luck, Mike
