Just picked up the 5.0 Mag Shootout issue!! My congratulations to JLT for posting the biggest gains!! My thanks to all the testers and the test subject owner for picking my system to remain on his Mustang. I've followed up with him on the production system I sent him and it's performed flawlessly. The prices listed in the article have changed due to the expenses involved with the polycarbonate heat shield and the custom molded 9" Green dual-cone filter. I went with quality regardless of expense. The system posted +24.4 rwhp gains.
