Combined for both!

Check out www.mach1registry.com as they did some dyno's on three different catbacks including the SLP. They were 4 valve motors however. If I recall, they got 10 or 12 rwhp for the SLP. MM&FF dynoed a '98 a while back with the catted X and got 22 rwhp or something close to that. Car had stock heads too.
