You'll get a lot of mixed opinions here, and honestly, up to this point, unless you're really maxxing things out (aftermarket turbos, fuel system, etc.) you're not getting a ton of difference in performance variation from one to the next. Pick the one that you think looks the best and or sounds the coolest, and send it. I personally really like the FenFab, but I've had SB products in the past, and I have some CT Motorfab things now, and they're also quality parts makers.
