BMW 428i F32 Custom Exhaust Upgrade

Precision‑Built Performance Enhancement
This BMW 428i arrived for a full DKU Performance stainless steel cat‑back upgrade, crafted to deliver the aggressive tone and aesthetic inspired by the BMW M4 Exhaust while maintaining premium build quality. Using high‑grade 304/316 stainless steel and smooth mandrel bends, our team engineered a free‑flowing system that enhances sound, performance, and durability.

Custom Cat‑Back System With 435i Dual‑Exit Look
We fitted a DKU Performance stainless steel back box and completed the setup with dual‑exit tips, giving the 428i a clean and striking 435i‑style rear profile. This system is fully bespoke, ensuring optimal flow and a refined, sportier exhaust note.
