Im looking for a new exahust for my supra and im debating between the RSR Gt2 exmag system which i hear is very light weight and is very straight, or the apexi n1 system which i dont know too much about, both are around $450 my friend as an apexi system on his fc and its LOUD. i know i can find the N1 at 935 motorsports but since the GT2 is discontinued i cant find it, does anyone know where to find it and opinions on which is better or if theres a better syetem than the two? thnx
