Fabspeed Pre-Muffler Pipe

Replace your outdated 964 factory catalytic converter with this straight-through resonated pipe to achieve increased horsepower, improved throttle response, and a throaty, gutsy sports car sound. Purpose: Enhances exhaust sound and provides significant power and torque gains by eliminating the restrictive factory catalytic converter while mitigating rasp and harsh tones with an integrated resonator.

Sound:

The straight-through design of this cat-bypass pipe delivers a much louder and throatier exhaust note from your 964. The integrated resonator ensures that this increased volume is accompanied by a smooth, deep tone without any unwanted rasp or harshness

Power:

Dyno testing on our DynoJet has demonstrated significant power gains across the RPM range, resulting in an increase of 16 whp and 14 ft-lbs of torque, which greatly improves throttle response.

Features:

• Increases horsepower by 16 whp and torque by 14 ft-lbs, significantly improving throttle response.
• Constructed from durable 14-16 gauge, T304L CNC mandrel-bent stainless steel for optimal flow and longevity.
• Features a straight-through resonator with stainless steel wool packing for long-lasting performance and effective sound refinement.
• Includes an integrated O2 sensor bung for precise air/fuel ratio management.
• Simple DIY bolt-on installation requiring the removal and replacement of only 5 pieces of hardware.
