FAQ
Does S6290409 require tuning or removing emissions parts?
No. It is a DPF/filter-back system. It bolts on behind the factory emissions equipment and does not require tuning.
Will it fit my 2017–2024 F-250/F-350/F-450 regardless of cab and bed?
Yes—this kit is designed for 6.7L Super Duty models across common cab/bed configurations. Always double-check wheelbase during install for tip alignment.
What tips work with this system?
Any compatible 4" system tip. Popular choices include MBRP T5155, T5157BLK, and T5081.
How loud is the “Tour” profile compared to stock?
It’s a refined, deeper tone—sportier than stock without being droney in the cab. Good daily-driver balance.
Is hardware stainless?
Yes—band clamps and hangers are stainless for long-term durability.
