SOUL Performance Sport Side Mufflers for 993 Porsche 911 Carrera

SOUL Performance Products Porsche 996 Carrera 4S Sport Side Mufflers are engineered around drone-fighting proprietary mufflers to deliver an exciting, refined driving experience, even with upgraded high-flow pipes. The design emphasizes the flat-six’s mechanical tone with more volume and character under moderate to aggressive throttle, while keeping an OEM-plus cabin presence during cruising to avoid rasp and unwanted drone. This configuration is selected with Polished tips for a clean, factory-style finish. Each system is built in-house at SOUL Performance Products’ Willow Grove, PA facility using mandrel-bent 0.065-inch wall, 2.25-inch diameter T304L stainless steel tubing, bespoke SOUL mufflers, and laser-cut brackets, with back-purged TIG welding using ARCAL Prime argon for durability. Every set is fixture-tested to confirm fitment, rigorously quality-checked, and foam packed before shipping, with new high-grade bolts, washers, and nuts included, and it is backed by SOUL Performance’s Lifetime Warranty for street and track use.

Development

• SOUL Performance Sport Side Mufflers are engineered around proprietary drone-fighting mufflers to preserve a premium driving experience while bringing out the flat-six’s mechanical character. The design increases volume and tone under moderate to aggressive throttle, yet maintains a refined OEM-plus cabin presence during cruising. SOUL Performance recognized that it is easy to make a 996 louder, but difficult to add aggression without ending up with rasp and excessive volume. Developed around SOUL Performance Sport Catalytic Converters, these mufflers deliver a true “gentlemen’s system” that stays livable for daily use, using ample sound-attenuating materials to add sporty character without drone or unwanted harsh notes.

Construction

• Each system is made in-house by SOUL Performance’s fabrication team using mandrel-bent 0.065-inch wall, 2.25-inch diameter T304L stainless steel tubing, bespoke SOUL mufflers, and laser-cut brackets. Back-purged TIG welding with ARCAL Prime argon gas promotes proper weld penetration and long-term durability, including demanding track use.

Bolt on and Go

• Each exhaust is built and fixture-tested by SOUL Performance using a thick-gauge aluminum jig to help prevent warping and confirm precise fitment. Every set is rigorously quality-checked prior to shipping and then foam packed to help ensure it arrives in perfect condition. New high-grade bolts, washers, and nuts are included.
