If you are going to lower it and get headers, you might want to stick with either MACs or some sort of shorty due to clearance issues. My car scrapes everything with the MACs because I am running a cat and it hangs lower than the y-pipe. If you are looking for all out power, go with LT's and I would suggest Jet Hot. They had a couple of batches that turned out bad but I have heard they worked everything out. A buddy of mine is running them with a lid, ram air and a little suspension and is pulling 350 to the ground. I know that is nothing new to you but I have seen the power they make and it is nice. Also, they were easy to install. Just something to think about. Good luck and nice #'s.

P.S. If you are looking to lower your car, you might want to look into www.thunderracing.com and get a package that they have. Its an Eibach Pro kit, BMR panhard rod, and BMR relocaion brackets. I got that package and substituted LCA's for the panhard rod. They were great to deal with and the price is good too, its on sale for $349.
