I was pleasantly surprised to the gains I picked up with these ISR headers. My previous setup I had hks exhaust, isr hfc, z1 race intakes and made 320/265. I switched over to these isr long tube headers and picked up a surprising 18 wheel hp over that previous setup. Car is now making 338/273! Money well spent! I only expected to make 10 wheel hp max over the hfc.
