Fi EXHAUST BMW G20 G21 M340i xDrive B58 (OPF) - Valvetronic Cat-Back + Downpipe

Fi EXHAUST BMW G20/G21 M340i xDrive B58 (OPF) - Valvetronic Cat-Back system + Downpipe





Fi EXHAUST G20 M340i xDrive B58 (OPF) product page: https://bit.ly/2HR8ybZ

Frequency Intelligent Exhaust provides the best of both worlds. It’s the perfect exhaust system for those who want to cruise in comfort and experience sport car resonance and Fi EXHAUST signature frequency at press of a button.

The Fi EXHAUST has been rigorously tested to offer the highest performance and optimal sound frequency through an optimal pipe diameter, CAD and innovative design, valvetronic technology, high grade materials and production process. The exhaust is built from a high grade stainless steel material and masterfully detailed and finished using TIG welding producing high quality and clean welds.

When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. When valves are fully open for maximum flow and performance it creates an exotic tone, intense sports car sound with signature Fi EXHAUST frequency.

Fi users can regulate a desired sound volume from quiet comfort to sporty aggressive using an OEM sport button. In sport mode valves are opened, which improves exhaust gas flow, increases sound volume and spices up exhaust note.



Fi users can also experience our vibrant exhaust sound on their own terms using our cutting edge Fi Pro Control System. Our sporty 2 button style remote control is lightweight, ergonomic and offers an intuitive way to switch between Street and Race sound profiles. The design is smooth and offers a nice grip, and the aluminum alloy ring can be customized in 14 different colors or switched to forged carbon ring with a unique marble like texture.

Take the personalization further with our Fi Pro App available both App Store and Google Play. Search “Fi EXHAUST Pro” to download and monitor real-time valve status with the help of our intuitive and user friendly interface. Assign Auto Mode preferences based on RPM/Speed/Turbo Boost. When Auto Mode is activated the system will intelligently open valves depending on the auto mode method and set data unit, for example, at 3000RPM.

Fi Pro Control System also address CEL issue after changing to an aftermarket exhaust. On an engine startup Fi uses can activate Auto Scan function to instantly scan and delete any CEL related to catalytic convertor. This function can be activated on Fi Pro App and is available on selected car models. Manual debugging is also available to remove unwanted CEL related to catalytic convertor.

For more motoring pleasure and sense of control. Fi collaborated with an aftermarket performance brand EINMS to provide our users G series paddles shifters that blend both aesthetic and function. The paddles have been extended by 40% compared to OEM for better reach and control. And designed with 100% bolt-on fitment covering the stock paddle shifters. The install can be done in under 60 seconds to completely alter look and wheel of the interior.



Finally, every Fi EXHAUST system is designed and tested to offer the highest possible performance output. And chassis dyno results showed incredible performance gains. The wheel horsepower was increased by 10.6% or 37.04 whp with Fi EXHAUST full catless system compared to OEM. Max wheel horsepower with Fi full catless system and OEM software was 385.75 whp @6598.61 RPM, however with OEM exhaust and software – 348.71 whp @5844.18.

  • Full turboback valvetronic exhaust system, which includes a front pipe, mid pipe, valvetronic muffler and catted/catless downpipes.

Exhaust sounds great. Those paddles are so unbelievably corny though! I'd rather drive a base model 3 Series with an M badge on the trunk than be seen with those ridiculous paddles.

Where do you produce your exhausts? In the US or in China?

Sounds great actually. I was not expecting that. Is it full Titanium? What's the price on the full system?

You guys really ripped off Akrapovic on the tips design though.

Hmm.... not sure. Kinda like my MPE setup a little more. Sounds too racy. Maybe that's just the bad mic used for filming.

I agree, I love the work they do across all brands, but they need a lot less cinematics and music playing over top what we really want to hear and see...

Thank you for the support. This version is made out a high grade T304 stainless steel.

We'll send a DM about the price inquiry.

Thank you the input and support. We'll try and address this in our produced videos. You should be able to find at least 1 video matching the set requirement on our YouTube channel.

To each its own. In collaboration with EINMS we've also developed paddle shifters for a BMW M steering wheel. They feature the M Performance tri-color stripe going nicely with the stitching and are finished in matte or gloss black.

What's your opinion on these?
