I have the Mugen unit. Top quality fit and finish. Install is a bit tight to actually get it in position, but once you've gotten past the obstructions it fits perfectly. Awfully expensive for about 10 ft of stainless steel tubing.
Performance wise, don't expect much above 7000-7500 rpm. I got zero gains, others have gotten 1-3 hp (I need to redyno and see if the ECU has adapted). However, from low rpm to 7000 rpm there are substantial gains in torque and hp. My peak torque went from 135-136 lbs-ft at the wheels to 139-140 lbs-ft. Average torque gain was about 5 lbs-ft and the max was 6-7 lbs-ft. Definite difference when driving back to back with a stock car.
