Our new M-7 V.A.L.E.™ exhaust systems feature our exclusive Teflon coated, blunted, cast magnesium
outlet and our exclusive X-Lite™ retaining ring. These exclusive Two Brother Racing features not only look
great, but also significantly reduce the weight of the exhaust system.
=
The V.A.L.E.™ inlet design eliminates the use of springs and creates an adjustable mount that is rock
solid when fixed in place. The system also features a precision mandrel bent, thinwall s-bend tube, and for
a full system, a header pipe custom fit for each model.

The P4 PowerTip™
was developed to fill the gap between the P1 and P1-X sound reducing tips. The P4 is more restrictive
than our P1-X but quieter than the P1, reducing sound output between 5-6 dB on most pipes. Power loss is minimal. Not
recommended for use with a spark arrestor screen.
=
Like all of our other sound suppressors, the P4 is very easy to install - simply unbolt your existing M-7 endcap, drop in the P4
and reassemble.
Note: The P4 is only intended for use with our M series outlets.
=
Our
P1 PowerTip™
sound suppressor is a recommended accessory for our exhaust systems with M series endcaps. A
straight-through sound diffuser, the TBR PowerTip™ quiets the pipe to about 3-4 dB with no significant reduction in horsepower.
Not recommended for use with a spark arrestor screen.

Easy to install

=
The P1X PowerTip™
sound suppressor is a recommended accessory for our exhaust systems with M series
endcaps. A straight-through sound diffuser, the TBR PowerTip™ quiets the pipe to about 7-8 dB with no significant
reduction in horsepower. Not recommended for use with a spark arrestor screen.
=

U.S. Forestry Service approved Spark Arrestors are included with all aluminum M-7 V.A.L.E.™ off-road slip-on
exhaust systems. These tips mute the exhaust tone slightly with absolutely no loss of horsepower. Additionally these
tips prevent the introduction of foreign matter into the exhaust system. This spark arrestor DOES NOT fit, nor is it
intended to be used with the C2, C4 or C5 mufflers.
