Do you allready have lt's? If you get rid of the y pipe and put in an x pipe, you will pick up a lil more power and alot more sound. Most people go with the dump, setup because its alot cheaper. Exhausts shops charge around 600$ or more to run true duals. You can pick up some bullett mufflers. Check out Thunderracing.com, one of our sponsers.

If you yank out your cats, you wont gain much Hp but a few. You can also pick up some cat bypass pipes, they bolt to your manifold and then to your y pipe, although you will throw a codes and the pipes are a little bit pricey.

i have shorty headers on my car i was thinking on putting long tube headers on it, is it worth it or should i stay with my shorty headers

you will see more hp with longtubes, i did especially if you get a tune. i would personally get rid of you cats and get magnaflow mufflers, they make a bullet style i think. they sound great and last a longtime. since you are in tarrant county they have emissions so that might be worth noting. btw what part of fw are you from? i moved up here from decatur about a month ago, welcome to the board
