it really depends on the application. i hear shorties do nothing for a basically stock motor, but with LT's and a tune you could see a nice power jump...shorties are more economical because they're basically a bolton, where as LT need the extra pieces of exhaust to fit right. long tubes will ultimately make more power across the board it all comes down to your preference of sound and the power level your going after.
