Soul Center Exhaust Bypass Kit – Porsche 991 GT3 & GT3 RS (2014–2019)

Description

The SOUL Center Muffler Bypass replaces the restrictive factory center muffler on the 991 GT3/GT3 RS/911R with a free‑flowing, mandrel‑bent stainless piping path — unlocking the flat‑six’s natural voice for a deeper, more aggressive exhaust note and sharper throttle response. It retains the stock side mufflers (and valve system, if equipped), giving you a perfect balance of race‑car vocal character and daily‑driving usability. Ideal for owners who want a dramatic upgrade in exhaust tone and flow without going full “straight‑pipe” territory.

Fitment Notes

• Fits all Porsche 991.1 / 991.2 GT3, GT3 RS, and 911R models (2014‑2019)

• Direct bolt‑on installation — designed to replace the factory center muffler and mate to existing side mufflers and exhaust tips.

• Does not remove or interfere with side mufflers or OEM valve system — retains factory exhaust valve functionality (if equipped), allowing “stock‑quiet” or “race‑loud” modes depending on valve position.

Included

• Mandrel‑bent T304L stainless steel center bypass pipe assembly

• All required mounting hardware and heavy‑duty clamps for secure connection to existing exhaust plumbing.

• Fitting components to mate with OEM side mufflers and exhaust tips, ensuring a clean bolt‑on install.

Product Specs

• Material: Mandrel‑bent T304L stainless steel tubing — corrosion‑resistant and built for high‑temperature strength.

• Install Type: Direct bolt‑on — designed to use existing exhaust hangers, flanges, and side mufflers. 

• Weight Savings: Approx. 11 lbs removed from the rear exhaust assembly compared to OEM center muffler.

• Sound Character: Produces a deeper, more aggressive flat‑six exhaust tone with more presence under throttle and at idle; preserves manageable drone levels for daily driving due to retained side mufflers. 

• Compatibility: Works with stock catalytic converters, side mufflers, valve system (where equipped), and factory exhaust tips — no special modification required. 

• Warranty: Covered under SOUL’s standard Lifetime Warranty for street and track use.

Product Features

• Enhanced Exhaust Tone & Character — By removing the restrictive center muffler and opening up the flow path, the naturally aspirated flat‑six gets a fuller, richer voice that lets the engine’s character shine.

• Bolt‑On, OEM‑Friendly Fitment — No cutting, welding, or modifications needed — installs using factory mounts and connects cleanly to existing side mufflers and exhaust tips.

• Balanced Performance & Usability — Retains side mufflers and valved exhaust system functionality, allowing the car to remain street‑friendly while delivering performance sound under throttle.

• Weight Reduction & Flow Improvement — Shedding roughly 11 lbs from the rear improves throttle response and exhaust evacuation, giving the engine a little extra liveliness and letting it breathe more freely.

• Lifetime Warranty & Proven Durability — Made from high‑quality stainless steel and fully backed by SOUL for street and track use, giving buyers confidence in long‑term reliability.

• Good Foundation for Further Mods — The improved flow makes this bypass an excellent base for upgraded headers, rear exhaust, or a full exhaust build — unlocking more potential from your GT3.
