LT's do make a difference even if you're sticking with the Eaton. Now to justify the cost is a different story. We've seen a 29rwhp gain on one of our customer's cars, but that's not always the case...most are in the 22-25rwhp gain. If $1200 (installed headers/midpipe) is worth another 20-25rwhp when you're all said and done, great, if not then they arent for you. They will also make the car louder, so you'd have to consider that as well
