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 Supertwin machines 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.
