EVO IV Silencer
We supply four short adapter pipes for a simple
modification of your heat exchangers, or you can
ship your HE's to us for modification.
This 100% stainless steel muffler is made to work with the stock design
heat exchangers, particularly with SSIs.
It’s only a little louder than stock, yet has the flow characteristics of a
straight through race muffler. The unique design fits the 914 body
perfectly and weighs significantly less than the stock muffler.
Midrange power is enhanced and the useful rpm range is extended all
the way to the stock engine's mechanical rpm limit of at least 6000 rpm.
It works equally well with either 1.7/1.8 liter or 2.0 liter Heat Exchangers,
and is suitable for engines up to at least 2056 displacement and 140hp.
Requires minor modification of your heat exchangers for installation.
Shipping is billed separately once we receive your order.
Estimated shipping price from CT to anywhere in the
continental US - not more than $75.
