The RDP Modified LB7 Intake Horn will increase the potential of your 01-04 GM 6.6L Duramax LB7 with this simple, but effective upgrade. Duramax LB7 owners now have the ability of connecting the turbo and aftermarket down-pipe back exhaust system by removing the restrictive stock pipe. The Rudy's down pipe provides a smoother flow from the turbo resulting in lower EGT's and increased performance. The down pipe is a relatively easy install due to the precision bends that you've come to expect from Rudy's.
