Soul Valved Exhaust Bypass System for Porsche 997 GT3 & GT3 RS (2006–2011)

Description

The SOUL Valved Side Muffler Bypass Pipes replace the heavy, restrictive factory side‑muffler sections with a lightweight, high‑flow stainless system — shedding roughly 35 lb and dramatically reducing heat soak. With factory‑style valves retained, you get a controlled, street‑friendly exhaust tone when closed, and unlock a louder, exotic, track‑inspired soundtrack when opened — offering the best of both worlds for daily driving or track use. It’s a bolt‑on solution engineered for fast installation and improved exhaust performance, while preserving valve‑controlled flexibility.

Fitment Notes

• Compatible with all Porsche 997 and 997.2 GT3 / GT3 RS (2006–2011) models. 

• Direct bolt‑on install — uses OEM mounting points, flanges and connections; no cutting or fabrication needed. 

• Fully valved design retains factory PSE-style control — exhaust flow is switchable between “quiet / street‑minded” and “full volume / performance” modes.

Included

• Full set of stainless‑steel side bypass pipes (left + right), with 3″ diameter mandrel‑bent tubing and factory‑style valve assemblies. 

• Flexible “bellows” sections to absorb vibration and thermal expansion under load — improving durability under street or track use. 

• All required hardware and gaskets for a straightforward bolt‑on installation using existing exhaust hangers and flanges.

Product Specs

• Material: T304L stainless steel, mandrel‑bent 3.0″ diameter primary piping, approximately 0.065″ wall thickness. 

• Weight savings: ~ 35.4 lbs compared to factory side mufflers (stock ~44.9 lbs vs aftermarket ~9.5 lbs).

• Valve system: High‑quality valves operate like OEM — allowing exhaust path to switch between quiet (valves closed) and full‑flow (valves open) modes.

• Piping layout: Large‑diameter straight‑through bypass for maximized exhaust flow to reduce back pressure and promote throttle response.

Product Features

• Major Weight Reduction & Heat Management — Removing heavy muffler units and heat‑soak zones improves rear-end weight balance, reduces exhaust‑bay temperatures, and helps keep rear tires cooler under track use.

• Switchable Exhaust Character — With the valves closed you retain a moderate, street‑friendly tone; open the valves and unleash a fuller, more exotic GT3‑style exhaust note.

• Enhanced Exhaust Flow — 3″ mandrel‑bent piping reduces back‑pressure and supports better exhaust scavenging, which can improve throttle response and exhaust efficiency.

• Durable, Track-Ready Construction — Premium stainless steel and flex‑bellows joints add reliability under repeated thermal cycling, making it suitable for both street driving and aggressive track sessions.

• Bolt‑On, OEM‑Compatible Setup — Uses factory mounting points, valve control, and exhaust outlets — making installation and reversion simple.
