I've always wondered why there is so much controversy with this mod. Is there a cheaper one besides a drop in K&N? People argue about which $400-500 catback makes more power when they are all within probably 2-3 hp. What people need to understand is that the whole package must work together. Think about it, would you put big cams on a stock intake, stock heads, no CAI, no tune, stock exhaust car and then be surprised when they don't show any gains? Plus, there has been some ricer math on this thread. A claimed gain of 20hp from a CAI+10hp from a catback+5hp from UDP does not equal a 35hp gain. The aftermarket has made outlandish claims for years on what the products actually do. They often change more than one thing on the tests if you read the fine print.
Bottom line, depending on what your other mods are, you may or may not see as much of an increase. If you want to go for it, do it, it's not expensive. If you think it's bunk, don't do it.
