ZD30 4 inch exhaust 😈 better than 3 inch 🙀
Just a video I found of my ZD30 ute feeding trees through the custom 4 inch exhaust with tear drop tip we made in house at RMR Diesel.
This is with +100 injectors prior to re tune. it made 270hp on stock nozzles and is now over 300hp. waiting to get back to Australia to continue R&D on it 😆
