DEVELOPMENT:  We wanted to design a costeffective Porsche Boxster valved exhaust that would offer the ability to go from “Cruising Sunday to Track Day” at the press of a button with the default setting to be valves closed for a more refined startup experience. Minimizing drone was also a priority. Porsche implemented a section of piping in the 986 Boxster exhaust that can easily be unbolted and replaced – a perfect location to incorporate valved dump tubes!

SOUND:  Don’t worry about starting up your Boxster in your garage – valves are closed by default! The OEM-driving Porsche characteristics and exhaust note are retained until you open the valves, and when you do, you’ll be treated to an aggressive bark as the mufflers are bypassed. Exhaust gases are routed out through dump tubes with valves open to give a flatsix roar.

CONSTRUCTION:  Each set of 986 Boxster fister mods is made inhouse by our fabrication team utilizing brand new OEM Porsche muffler piping and applicationspecific valves with a closed mode by default.

BOLT ON AND GO:  Each Boxster exhaust is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment. Every Porsche 986 exhaust set and valve controller kit is rigorously quality-checked prior to shipping.

LIFETIME WARRANTY:  Enjoy your Porsche 986 Boxster Muffler Delete and all other Soul exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.
