Installation was mostly straightforward. The only reason for a lower rating was that the exhaust pressure sensor didn’t align with the bracket. I found a proper solution myself and secured it correctly.
Only reason this isn’t five stars is the repeated trips for hardware. Do yourself a favor and grab a few extra flange bolts ahead of time.
I should have done this years ago. The process was simple and the truck now sounds and performs the way it should have from the factory. Fuel mileage improved by about 6 MPG.
Ordering was simple and support quickly resolved an initial file issue. Exhaust install was easy and the 5-inch option sounds great. My only complaint is not knowing exactly what each tune does.
This is exactly what the truck needed. It finally feels open and responsive like it should have from the factory.
