Without a tune, Yes in lower RPM's but a tune can help you with the loss and will help you pull even more power out of it. When I put my LT's and catback on I noticed a slight drop in power under 2500 RPM's but after that it's like night and day the extra power I got.

Since you are stock, many other bolt-ons I would do first = See sig., my next mod will be LT with Cam and tune. I have gone 12.40s without LT headers, looking to get into 11's full weight w/ cam.

I had heard that and was a little concerned about it. With my LT's, I ended up not losing any low-end torque and probably gaining a little. They feel really good at part-throttle around town. So far I haven't gained much overall performance with them, though. The jury's still out on whether they were worth the hassle and expense.
Along the same lines, my buddy's car with Pacesetters/ORY would run neck and neck to mine with manifolds/cats. The cars are both 2000's with very similar mods. I don't think he saw a lot from them.
