The Vetterman 4-pipe exhaust system is the only COTS (commercial-off-the-shelf) kit supplied system available at this time to fit the ECi cold air intake and Silverhawk EX fuel servo. The kit went on as advertised in a minimal amount of time. Photo 3 shows the top half of the dual-pipe heat muff. Final installation of all brackets and supports is not complete in these photos.
