Message My understanding is the 3" down pipes and exhaust reduce the amount of back pressure on the turbos which helps the turbos to spool up quicker. I'm not an expert but there is suppose to be a big gain going from 2.5 --> 3". I sure hope so because they are on the way! Good luck in your search.
