bought it from summit, made for ls3 with magnuson supercharger, cost 499.00 with 50. rebate from airaid. i liked the carbon fiber pipe,but it is too long for the eaton supercharger connection. so i got my angle grinder out and marked the pipe for correct angles then cut it. had to drill new holes for maf sensor block and pvc nipple pipe. spent 4-5 hours making this work, this does change the intake sound and more throttle response at lower rpm.
