M4 exhaust systems & slip-ons

M4 exhaust systems

JHS are the sole UK agents and importers of these very high quality, US-made performance exhaust systems.

One of the reasons we choose M4 pipes is that the dyno graphs shown on their site match our experience of the true power to be had from these systems. Our graphs have not been 'tweaked' to show the power we want to show, they show what the bikes really make with these pipes - and they certainly deliver!
