More Power. Improve throttle response and increase horsepower and torque with a Grand Rock Dual Smoke Stack Exhaust for your 99-03 7.3L. By improving exhaust flow you'll improve your turbo's performance and set the stage for future mods.
Lowers Backpressure and EGT's. Improve exhaust flow and increase performance with the 5" primary tubing and 4" downpipe of this Grand Rock Diesel Exhaust kit. You'll reduce backpressure and your EGT's, allowing you to add more mods without worrying about damage to your engine.
36" Dual Mitred Stacks. The dual 36" chrome stacks of this Grand Rock exhaust kit end at the top of your SuperDuty's cab for "big rig" style. Coming right out of your bed behind your cab, their impressive 5" diameter and mitre cut tops are the perfect aggressive look for a serious, take-no-prisoners type truck.
Premium Quality. Unlike other aftermarket manufacturers, Grand Rock's exhaust kits are designed for an easy installation with no length adjustments required to the tubing. They also include other details to ensure your Grand Rock kit lasts just as long as your Powerstroke, like remetalized, coated welds, zinc coated brackets, and high quality AccuSeal clamps.
Complete Kit. AmericanTrucks is proud to offer this exhaust as a complete kit for your race-ready Powerstroke, from the back of the turbo to dual chrome stacks.
Application. This exhaust kit is designed to fit 99-03 F250 and F350 SuperDuty trucks with the 7.3L Powerstroke Diesel engine.
