I did it to both our cars based on advice on the board, but I haven't noticed any gain other than aural. Actually, the GT came with a JC intake. I hated it because it starved the plenum of air under sudden WOT inputs (like stop signs at the ends of entrance ramps under construction- not fun). So I put the torque chamber back on, butI can't see how the snorkus really restricts anything- it is just a big secondary reservoir, nothing inherently restrictive about it. Truth be told, I am becoming highly skeptical about the benefits of any intake mod on a Soob, especially ones with a MAF, unless attention has been paid to the torque chamber issue.
