*68" Top Stacks Will Equal A Total Of 14' Off The Ground! Buy With Caution!

Optional Y-Pipes:

Standard Dynaflex lower elbows reduce to 5" under the truck. Y-Pipes are available in 5" diameters and allow you to retain your stock flex piping. Choose between aluminum or chrome plated finishes in the 5" Y-Pipes. Also available is the Full Diameter Y-Divider Combo, which upgrades your exhaust package to 90-Degree elbows with no 5" reduction, and upgrades the Y-Pipe to the full diameter of the rest of the exhaust system. The Y Pipe reduces to 5" at the front of the piece to mate with the stock 5" exhaust. 

The 8" Dynaflex chrome exhaust kit is custom made for Peterbilt 359 and 379 models. The Peterbilt 379 trucks use a 58 degree elbow and the 359 trucks use a 68 degree elbow. The 90 degree elbows will work on both models. The kit includes 2 top stacks, 2 center spools, 2 lower elbows, 1 pack of 8 urethane bushings, 4 clamps, and the appropriate cab brackets for your truck.
