This stinger open exhaust system is designed to easily bolt on to the factory heat exchangers or SSI's, in
headers on 65 to 89 911’s, or with S pipes on short headers.
The merged pipes create a scavenging effect that increases both bottom end and mid range power and
torque. This feature makes it an excellent alternative to megaphones, especially for tracks where gearing
is not ideal and that extra amount of low/mid range pull makes all the difference.
