DEVELOPMENT AND TESTING: Deleting the side mufflers yields huge weight savings and helps with heat management in the engine bay and also keeps the rear tires cooler. The hole leading into the secondary pipe is enlarged to equalize pressure in the center muffler – reducing chances of it cracking. Flex bellows allow for easy installation and prevent cracking under extreme racing conditions. Large 3″ diameter primary piping increases flow.

SOUND: Expect an increase in volume without any negative notes in tone – in fact you’ll be treated to a more exotic / race derived experience. Increased cabin presence will be noticed in the 2,000-3000 RPM range while the exhaust note above 5,000 RPM will sound even more incredible!

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 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.

    I just installed the SOUL Side Bypass Pipes (non-valved) on my 991.2 GT3 and the sound is awesome. I almost didn’t go for these because of some reviews of loss of torque / throttle response, and drone, but as per many others here, I’m not experiencing any of the above. I’m tolerant of a little drone so maybe don’t take my word for that, but I wouldn’t accept a loss in throttle response or torque and I’m not feeling any of either.

    I had the Sharkwerks center bypass with valves disconnected on my 991.1 GT3 which I thought was great (almost did the same thing here again since this is strictly a road car for me, and I am more concerned about sound than weight/heat) but the side bypass pipes are fantastic, all-round. Amazing tone/richness/depth, quiet enough on low throttle for around town (I definitely don’t need valves for my volume tolerance), and like others have said, it really retains the stock noises, just with a little more/better sound, proper exotic cup-car like tone, just quieter. At some rev levels it barely sounds different than stock inside the car.

    Thanks to John @ SOUL for the great service & advice on this one (always available for a call or email), considering how many options there are now, happy I ended up with the perfect set up for me.
