DEVELOPMENT:  We set out to craft a full valved catback exhaust system that would offer great power gains with valves open, a stealth mode with valves closed, and a premium experience without the premium price – we don’t believe in the “M tax”. With valves open, exhaust is free to exit straight through an x-pipe to smooth the tone and 2.75″ piping for maximum power. RK-Tunes reports that our development M4 made over 10whp more than similar cars with identical mods prior to a tune – the highest horsepower untuned car they’ve ever baselined.

SOUND:  Choose between Resonated and Non-Resonated exhausts. We recognize that a large amount of owners upgrade to catless downpipes, which can add harshness and raspiness to any exhaust setup. As a result we offer optional resonators which can help with minimizing some of the metallic bite and bark when aftermarket downpipes are used. Each combination has a unique tone:

Stock Downpipes + Non-Resonated Exhaust:  Get a more aggressive tone than M-Performance at a better value.
Stock Downpipes + Resonated Exhaust:  Adding resonators with stock downpipes transmits more tone into the cabin (a very slight perceivable rumble that you can feel – which we enjoy) while quieting down the exhaust from the outside slightly. Valves closed will sound like factory – full on stealth mode.
Aftermarket Downpipes + Non-Resonated ExhaustIf you want an all out, aggressive note (especially with burble tunes) the full song of the S55 is unleashed. For when you like the raw sound of straight pipes, but still want to be able to drive through your neighborhood at night.
Aftermarket Downpipes + Resonated Exhaust:  Resonators take some of the harshness / rasp out of the exhaust note and smooth the transition between valves closed and open. Maximum power with as reserved a sound as possible for a street car.

If you have any questions about which system is perfect for you, please contact us.

CONSTRUCTION:  Each system is made from mandrel bent .060″ T304L stainless steel tubing and incorporates a high quality muffler made with fortified casings in the interest of durability – built to withstand the abuse of 600+ ft-lbs of torque. We use high quality Mikalor Supra Heavy-Duty T-bolt clamps to hold the exhaust tips securely onto the system. The outer tips have a 1/2″ of adjustment for tip depth whereas the inside tips can be setup staggered like the OEM exhaust or flush for a unique look. Our black satin tips are PVD coated for a long lasting, heat proof finish.

Default tip sizing is designed for the OEM / OEM style diffusers. For extended aftermarket pieces such as the Vorsteiner carbon fiber diffuser, we offer 1″ longer tips. We recommend selecting the OEM diffuser style if your diffuser is not aggressive.

BOLT ON AND GO:  Each exhaust is tested in a fixture to ensure perfect fitment. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts. Valve functionality is just like OEM and the factory actuators are reused.

LIFETIME WARRANTY:  Enjoy your SOUL exhaust with confidence on both the street and track as it’s covered by our Lifetime Warranty! Our team will quickly work with you to answer any questions or resolve any issues that you may have.

+  This exhaust deletes the secondary catalytic converters, is not CARB certified, and may not be legal for use on emissions controlled vehicles; intended for off road use only
+  We do not recommend aggressively driving the car with valves closed at high RPM using an aftermarket valve controller. To achieve such a reserved sound with valves closed the internal muffler pipe sizing is reduced (like most valved systems) – great for tone but not ideal for performance.

    I switched out from another aftermarket exhaust to Soul’s non-resonated system in search of a better sound. Not only does it sound insanely good but I set the baseline record for M3 / M4 on RK Tune’s dyno which tells me I made the right choice. Thank you guys!

    Love this exhaust and the performance from it. Before this exhaust I had an esienmann exhaust with evolution racewerks down pipes and while the sound was good it was fairly raspy. Now remember this is an inline 6 and there’s only so much you can do with it. However this resonated exhaust from soul makes everything a lot better. The sounds and the burble are dignified and not just all over the place. There is little to no drone inside of my cock pit and I’m able to hear the person next to me speaking without screaming. I’ve had this setup for about 2 months now and really love the sound and performance of it. My car feels smoother and I love the look it gives the back end. If you do go there to get it done they do do a walk over with you and your car and take very good care of it as I left mines there for a weak so they can play and my car came back in the same beautiful way it was. The customer service is outstanding and if there’s something you don’t like they will help to fix it and do their best to fix the situation as much as they are capable of doing.

    I like to say, wait no. I love to say, that these guys are the best in the market. Not to hype it up, but their exhaust and also the staff work together as a unique team. I never seen a staff that treats you so well and at the same time give you the best and most amazing exhaust performance out there. What it cost is not even close to what this exhaust system perform. I recommend it and no one please dont hesitate in getting it because it’s worth it. My Instagram with their exhaust is @bimmer_journey

    Catback non-res M3 F80 exhaust with stock down pips and CF tios – Can’t say enough about this setup,the sound is great inside and out. I had the Akra Evo before this and can definitely say this has better sound thoughout the RPM range. Absolutely no drone and carbon tips look great. The price is just right.
