EVO IV Silencer

EVO 6 EVO IV Silencer

Tangerine EVO IV Dual Outlet Silencer

This is a 100% stainless steel muffler made to work with the stock exhaust system/ heat exchangers.
It is no louder than stock, yet has the flow characteristics of a straight through race muffler.
Power and rpm range are extended all the way to the engine's mechanical rpm limit of at least 6000 rpm.



The muffler requires minor modification of your heat exchangers for installation.
The flanges must be cut off and 4 short adapter pipes welded in place.
It works equally well with either 1.7/1.8 liter or 2.0 liter (stock or SSI) Heat Exchangers,
and is appropriate for engines up to at least 2056 displacement and 150hp.

The muffler is available shipped with the four adapter pipes for you to modify yourself,
or you can ship your HE's to us for modification.
Also available, complete systems with modified SSI Heat Exchangers.
A stealth version of the muffler can also be made so you don't have to alter your rear valence.
