Soul Long-Tube Street Headers for Porsche 987.1 Boxster and Cayman (2005–2008)

Description

The Soul Performance Long Tube Street Headers are a high-flow exhaust manifold upgrade engineered for the Porsche 987.1 Boxster and Cayman (2005–2008). By replacing the restrictive factory cast headers with precision-mandrel bent, equal-length long tubes, this system dramatically improves exhaust scavenging and flow efficiency. The result is stronger midrange torque, improved throttle response, and a deeper, more engaging exhaust note that enhances both street driving and spirited canyon runs. Constructed from durable stainless steel and designed for a mostly OEM-style installation, these street headers are a core upgrade for enthusiasts seeking everyday-usable performance gains.
