Description:

This stinger open exhaust system is designed to bolt on to the factory heat exchangers, in place of the stock muffler on all 65 to 73 911’s.  It can also be used with long headers on 65 to 89 911’s, or with S pipes on short headers (with 65 to 73 muffler spacing).

The merged pipes create a scavenging effect that increases both bottom end and mid range power and torque.
