Soul’s 991 Turbo Cat Bypass Pipes removes the restrictive factory catalytic converters and replaces them with straight-through 3″ stainless steel piping. The result? Sharper throttle response, more aggressive turbo spool sound, and a new, raw exhaust character — especially on throttle and deceleration.
Fitment Notes
Fits Porsche 911 (991.1 and 991.2) Turbo / Turbo S models (2013+).
Direct bolt-on: includes hardware and instructions for a straightforward DIY installation.
Because factory cats are removed, the system may trigger a Check Engine Light (CEL) — Soul recommends either O2 sensor spacers or a custom ECU tune.
Not CARB-certified — intended for off-road or competition use.
This component requires signing Soul’s “Catless Exhaust Component” waiver for U.S. customers.
Included
Two (left + right) bypass pipes made from 0.065″ T304L stainless steel.
Mounting hardware and gaskets.
Installation instructions.
Lifetime warranty documentation (covers both street and track use).
Product Specs
Material: Thick-wall (0.065") T304L stainless steel with smooth mandrel bends.
Weight savings: ~ 10 lb (4.5 kg) lighter than stock factory sections.
Pipe diameter: 3 ″ — selected to maximize flow and turbo spool sound.
Emissions: Removal of cats may affect emissions legality.
Other notes: May require O2 sensor spacers / tuning to avoid CEL.
Product Features
Improved Turbo Sound — Without the restrictions of factory cats, turbo spool and crackles are more pronounced and engaging.
Better Throttle Response — More free-flowing exhaust helps reduce back pressure and sharpens response.
Lightweight Construction — The thinner, mandrel-bent stainless steel reduces weight over the OEM catalytic setup.
Build Quality — Made with premium T304L stainless steel and expertly welded with water-jet cut flanges for long-term durability.
Backed by Warranty — Soul’s lifetime warranty gives confidence for both street and track driving.
