FAQ
Will this system delete or modify emissions equipment?No. This is a DPF/DEF-back (“filter-back”) exhaust. It keeps factory emissions components in place.
Do I need tuning after installing this exhaust?
No tuning is required. This is a bolt-on, cat-back/filter-back-style upgrade designed for stock emissions systems.
Will it fit my long bed / crew cab?
Yes—MBRP includes tubing for common wheelbase configurations. Some trucks may require trimming per the instructions.
Any clearance issues with a 35" spare?
Trucks running a 35" spare may need to relocate the spare for proper clearance.
