DEVELOPMENT AND TESTING:  Deleting the side mufflers yields huge weight savings, helps with heat management in the engine bay, and keeps the rear tires cooler. The hole leading into the secondary pipe is enlarged to equalize pressure in the center muffler – promoting longevity. Flex bellows allow for easy installation and increase durability under extreme racing conditions in a similar manner to OEM. Large 3″ diameter primary piping increases flow. High quality valves operate like factory.

SOUND:  The sound is smoother during the transition between open and closed versus a center muffler bypass. Valves closed tone is increased moderately while still comfortable with factory center muffler in place. Valves open reveals a refined, exotic pitch befitting of the high performance GT3 engine.

CONSTRUCTION:  Each set is made from mandrel bent T304L 3″ .065″ wall stainless steel tubing and high quality flex bellows for maximum durability.

BOLT ON AND GO:  Each exhaust is tested in a fixture to ensure perfect fitment and then foam packed to arrive in perfect condition, ready to install with no cutting or modifying required.

LIFETIME WARRANTY:  Enjoy your SOUL exhaust components with confidence on both the street and track as the valves and entire exhaust 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.

NOTE: O2 bungs can be added (to work with aftermarket headers that relocate the bungs to the SMB). We do not add them by default in the interest of lightness. Contact us for this option.

    Weight savings:
    Confirmed on the scale, solid weight loss of the rear of the car as advertised.

    Reduced heat:
    This was VERY noticeable as soon as I removed the side mufflers and installed the valved bypass pipes. The engine compartment is WAY cooler after a long drive compared to when I had the side mufflers on the car. Very Impressed with this .
    Tire pressures are more stable in the rear as well ( due to reduced heat in the back I believe).

    Performance:
    I’ll be honest here, nothing to notice in regards to power gains ( I did not dyno the car as I wasn’t looking for gains anyways).

    Sound:
    FANTASTIC ! I’m running the car with race headers ( catless) and it is absolutely addictive. In normal mode it sounds tame , no drone at all and can be driven daily without annoying anyone ( perhaps 20% louder than stock) . Sport mode is a different story lol ! The closest thing is ( if I wanted to describe how it sounds in words) would be a 997 cup car. Really aggressive, heel toe is way more pronounced compared to the stock setup and throttle blips just rip.
    Really satisfied with this aspect. I would easily say this is the BEST exhaust solution for a GT3 if you are looking for sound + weight saving.

    Quality and packaging:
    Professional packaging , really nice quality and welds on the bypass pipes as well.

    Install:
    If you can put together Legos, you can install the bypass pipes on the car.

    Really satisfied with the purchase John, two thumbs up !
