DEVELOPMENT: Our goal was to create lightweight, robust, cost-effective exhaust components for the GT4 that are readily available, perform well, and are built to last. Through feedback and long R&D conversations with various shops, technicians, and drivers that have done their own independent testing over the years (a special thank you to Bryan Schute at Speed Sport Tuning and the team at LN Engineering / BRS) we came up with a game plan for a track bred system.
PIPING: Over axle pipe profiles are full 2.5” piping diameter and were designed to leave sufficient clearance for the axles and sway bar end links on heavily modified / lowered vehicles.
BESPOKE BRACKETS: Hangers and brackets welded directly to the exhaust have a tendency to break under racing use – a quick way to ruin a track day. SOUL’s mounting solution sheds over 5 lbs compared to the factory mounts and our components are easy to repair or replace in the event of a track incident. The forward piping is connected to a bespoke SOUL trans mounting brace via heavy duty Mikalor band clamps. We’ve added additional support to the over axle piping through rubber vibration dampeners to reduce the stress of flex and vibrations on the entire exhaust system.
CONSTRUCTION: Each system is made in-house by our fabrication team from mandrel bent .065″ wall, 2.5″ diameter T304L stainless steel tubing. Brackets are laser cut, press brake bent, then TIG welded for maximum durability. All welds are back purged for increased longevity under the most extreme conditions.
SOUND: This racing system was designed primarily for track use and performance over sound attenuation – it will be VERY LOUD, and even with resonators drone will be present. We do not recommend attempting to run this exhaust with aftermarket headers on the street. That said, it sounds absolutely amazing at full bore. If you’re looking for a more refined exhaust experience for street use, consider our Valved Exhaust System.
BOLT ON AND GO: Each exhaust is rigorously quality-checked, tested in a fixture to ensure perfect fitment, and then foam packed to ensure it arrives in perfect condition. New high grade hardware is included for the header to exhaust flanges. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
