UNLEASH THE FLAT-SIX

Even a premier engineering masterpiece like the GT3 comes from Porsche fitted with exhaust manifolds restricted in terms of primary tubing length, runner diameter, and merge collection efficiency due to dense catalytic converters, mass production, and emission restriction compromises.

ENGINEERED FOR PERFORMANCE

By refining the interface between the flange/primary tubes, using smooth radius large diameter bends, and implementing performance-oriented collectors with merge spikes, Soul has achieved increased flow, response, and performance with a more aggressive exhaust note to match.

CNC BILLET MERGE COLLECTORS

A slip-on merge collector was not considered to prevent any chances of exhaust leaks. Instead, Soul focused on designing a high-flow collector from CAD to CNC for a no-compromise end result. This bespoke billet collector allows for maximized runner length and the elimination of several welds in the interest of durability.

5-AXIS CNC HEAD FLANGES

Billet 304L stainless steel head flanges are precision cut on a 5-axis CNC machine for the best possible exhaust flow and strength. The refined interface between the flange and primary tubes ensures optimal flow characteristics from the moment exhaust gases leave the cylinder head.

CONSTRUCTION

Each header set is assembled in the USA out of mandrel bent, thick wall .065″ T304L stainless steel. Back-purged TIG welding with ARCAL™ Prime argon gas ensures proper weld penetration and longevity – crucial for durability on the track. Headers are fabricated using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping.

LIFETIME WARRANTY

Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered for life!
