Porsche 997.1 Carrera Valved Exhaust

The unique valved exhaust design of this 997.1 muffler offers a sporty OEM+ sound with valves closed and a race-inspired sound with valves open. The default valve orientation upon startup is valves closed for a more refined warm-up experience, and an invigorating tone reminiscent of air-cooled CUP cars is just a button press away!

DEVELOPMENT: We wanted to design a valved exhaust that would offer the ability to go from "Cruising Sunday to Track Day" at the press of a button with the default setting to be valves closed for a more refined startup experience. Following the extreme effectiveness of the Porsche mufflers used in our 987 / 981 exhausts to combat drone, weĂve applied the same design principles to a bespoke muffler for the 997 Carrera.

SOUND: The design of our exhaust channels exhaust gases through our bespoke mufflers for a sophisticated and sporty sound that is unmistakably Porsche with valves closed, and this is the default operation setting. With valves open, youĂre getting a CUP-inspired straight pipe sound. With valves closed during cruising, there is no drone - even with aftermarket catalytic converters! Due to the aggressive, free-flowing nature of the valves-open mode, the volume is loud when paired with aftermarket catalytic converters or catless replacement pipes.

CONSTRUCTION: Each system is made in-house by our fabrication team from mandrel bent .060" wall T304L stainless steel tubing, bespoke SOUL mufflers, and laser cut brackets - with well over 15 man hours invested in each set of Porsche valved exhaust components to make sure they are perfect.

BOLT ON AND GO: Each exhaust is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment. Every set is rigorously quality-checked prior to shipping.

LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered with a Lifetime Warranty!
