Soul Modular Competition Exhaust System for Porsche 991 GT3 & GT3 RS (2014–2019)

Description

The SOUL Modular Competition Exhaust Package delivers a flexible, race-ready exhaust upgrade for the 991-series GT3 / GT3 RS / 911R. Engineered with modular side- and center-muffler bypass options, this system allows you to tailor exhaust sound and flow to your driving needs — whether that’s aggressive track tone or a more refined street presence. Built from mandrel-bent T304L stainless steel with heavy-duty clamps and custom support brackets, it combines serious performance gains with reliable durability. With up to ~46–49 lb weight savings compared to stock, it enhances throttle response, reduces rear-end heat soak, and gives your car a more visceral exhaust note.

Fitment Notes

• Fits Porsche 991.1 / 991.2 GT3, GT3 RS, and 911R (model years 2014–2019)

• Available in valved and non-valved configurations — valves free up exhaust flow while retaining OEM-style PSE valve control (on valved version).

• Modular design — you can mix and match side-muffler bypass, center bypass, or full delete to dial in sound and performance according to occasion (street drive, canyon carving, track day).

• Direct bolt-on fitment — uses existing exhaust mounting points; no cutting or welding required. 

• Compatible with the stock O₂ sensor placement (sensors remain in the header), so no check-engine lights.

Included

• Side-muffler bypass pipes

• Center-muffler bypass exhaust section (with expansion chamber for balance between flow and interior NVH)

• Bespoke heavy-duty support brackets (to replace factory muffler supports when the OEM components are removed)

• All required hardware and clamps (heavy-duty W4-class clamps, gaskets, brackets) 

• Option of exhaust tips (various single-wall tip finishes/styles) depending on configuration choices

Product Specs

• Material: Mandrel-bent T304L stainless steel tubing — durable and resistant to heat/thermal stress.

• Weight Savings: ~ 46 lbs (valved config) or ~ 49 lbs (non-valved full bypass) vs stock rear muffler/center-muffler combination.

• Modular Configuration: Side bypass + center bypass in any combination — allows tuning of sound level and back-pressure depending on use (street vs track)

• Valved Version: Retains factory valve control — keep it quiet for daily driving or open it up for full race tone

• Non-Valved Version: Fully open exhaust flow for maximum sound and minimal restriction — best for track/competition use.

Product Features

• Fully Modular Exhaust Architecture — Swap or combine side and center bypass sections to dial in your ideal balance of sound, flow, and drivability. 

• Significant Weight Reduction — Shedding ~46–49 lbs reduces rear-end mass, contributing to sharper throttle response, better handling, and improved balance. 

• Valved & Non-Valved Flexibility — Choose between a valved setup for versatility (street-friendly to track-ready) or non-valved for uncompromising performance. 

• Durable, Track-Ready Construction — Using heavy-gauge T304L stainless with high-quality clamps and mounting hardware ensures longevity and resistance to heat or corrosion. 

• No Check-Engine Light — O₂ sensors remain in the header, so the exhaust swap doesn’t trigger codes, even in the non-valved full bypass configuration. 

• Lifetime Warranty — Backed by the manufacturer for both street and track use — offering peace of mind for high-performance builds.
