DEP is a specialist English company that, with great care, has been building exclusively exhaust pipes and silencers for off-road competition bikes since 1978.
The pipes stand out for the even power delivery across the entire rev range, as they are designed for motocross and European tracks. Some pipe models made with reinforced, thicker sheet metal are also available, typically for enduro use.
It is important to note how closely the pipe hugs the frame, making it less exposed to impacts.
If the pipe has a natural finish (not nickel-plated), after each wash it must be protected from surface rust (for example with an oily rag).
