depends on the car. the 99-04s have a bit of restriction at the y- but go too big and you lose hp. you can pick up a good amount switching to 2" duals -but 2.5"ers lose you a ton of hp/tq.
Unless you're running a power adder.
anything older than that, and it's appearance only. -again unless you've got something else going under the hood. .. .
Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
