An axle-back exhaust for our cars are not the most restrictive part. It's especially the catalytic converters right after the headers and then midpipe. You can refer to the link on the gains for the f-sport exhaust which is essentially a re-branded hks axle-back exhaust. http://www.importtuner.com/powerpage...s/viewall.html
