Overview

The SOUL Sport Cats / Cat Bypass Pipes replace the dense factory catalytic sections on the Porsche 997.1 Carrera, the most restrictive part of the system after the engine itself. Less back pressure means quicker response, more top-end pull and a richer 3.6L flat-6 / 3.8L flat-6 / 3.6L / 3.8L flat-6 sound.

SOUL Performance Products designs, builds and tests its exhaust parts in-house in Willow Grove, Pennsylvania, and has developed many of them on its own track and street cars. Parts are covered by a lifetime warranty for street and track use.

Options on this page: Cat Section: Cat Bypass Pipes (Catless), Sport Catalytic Converters (Catted). Factory Exhaust: PSE, Non-PSE. Catted choices use high-flow catalytic converters for street use; catless choices replace them with straight pipe for maximum flow.

Features

  • Replaces the restrictive factory catalytic sections
  • Bolts to the factory or SOUL rear exhaust
  • Choice of catted or catless configuration where offered

Fitment notes

  • SOUL fitment: Fits all Porsche 997.1 Carreras (2005-2008) – note different part numbers between non-PSE and PSE exhaust equipped cars.
  • Catless parts remove emissions equipment. They are sold for off-road and closed-course competition use only and are not legal on public roads in emission-controlled areas.
  • SOUL notes that this part can set a check engine light; an ECU tune is required to run it correctly.
  • Professional installation is recommended. Questions about fit on a specific car: Online@AutoTalent.com.
