Our small oval M-2 V.A.L.E.™ exhaust
system features our exclusive Teflon coated, blunted, cast magnesium
outlet that not only looks great but also allows for various
silencer inserts.
The V.A.L.E.™ inlet
design eliminates the use of springs and creates an adjustable mount
that is solid when fixed in place. The system also features a
thinwall s-bend tube that connects to the factory header pipes. |
