Not saying if you should or should not, just trying to help you make an informed choice. Something that I wish people would have done for me in the past. You can call me a "hater" if you want, I could care less. You might see a drop in TQ from the loss in back pressure, but you should also see some HP.
I know alot of f-body guys use the QTP stuff and seem to like it. If I were to put one on that would be what I would use. I would take a look over on LS1tech and Camaroz28.com for some good info.
