M4 exhausts: full racing exhaust systems
JHS are the sole UK agents and importers of these very
high quality, US-made performance exhaust systems.
We use M4 pipes with the Mini Twins race bikes that
we build. We choose M4 because the dyno shows that
no other pipe can deliver such dramatic gains from
the Suzuki SV650 engine, while offering outstanding
build-quality at a competitive price.
M4 exhausts are available for a range of fitments
and motorcycles.

All
M4 systems will increase power output of your
motorcycle over its stock system, but to gain the most benefit we
recommend that the system is installed by one of our expert
fitters and the bike is then checked on our dyno.
