DEP Pipes are one of the only aftermarket motocross exhaust pipe manufacturers to produce 2 and 4 stroke exhaust systems. The S7 is DEP's market leading 4 stroke exhaust system, complete with Power Boost header pipe and a black anodized carbon end capped silencer, all of which complies with FIM noise restrictions of 94dB. Then there is the S7's little sister the new S3 Silencer range manufactured for the leading Enduro and trail riding model motorcycles.
2 Stroke's are not dead and buried and DEP pay special attention to producing what is believed by many as the best performance 2 stroke systems available, and produce a huge range including older model bikes.
