The MagnaFlow SPEQ Series #19828 cat-back exhaust is engineered for BMW G20, G22, and G23 M340i/M440i and xDrive models equipped with the 3.0L B58 inline-6. Designed to improve exhaust flow, amplify performance sound, and enhance visual appeal, it aggressively elevates the character of modern BMW performance. Constructed from mandrel bent 3” 304 stainless steel tubing with a 3.5” front pipe, it offers excellent durability and corrosion resistance. A stamped Y-pipe smoothly merges exhaust pulses for improved efficiency, while the straight-through design is dyno proven to support power gains for both stock and high output applications. Sound is managed through dual 5x8” straight-through mufflers and an NDT resonator, producing a deep, aggressive performance tone under acceleration while eliminating drone at cruising speeds. The result is a strong, assertive exhaust note that stays controlled in daily driving and opens up with pops and cracks when you get on or off the throttle. The system features interchangeable tip options secured with racing bred V-band clamps for a leak free, heat stable connection. Choose quad 3.5” black chrome tips with laser etched MagnaFlow “MF” logos or reuse factory tips. OEM valve functionality is retained by MagnaFlow’s cast stainless valves, allowing full integration with all driving modes. Designed as a direct replacement for factory components behind the catalytic converters, the system includes band clamps, laser cut logo brackets, and all necessary installation hardware for a secure, precise fit, achieved through 3D scanning and CNC robotic manufacturing ensuring a true direct-fit installation. Backed by MagnaFlow’s limited lifetime construction warranty, this cat-back delivers a measurable upgrade in sound quality, flow efficiency, and overall power. Designed with a focus on real world performance, it enhances the B58 with a power focused exhaust tone and the premium construction demanded by modern high output performance.

Easy people to deal with and friendly. Will do business again with them.
The staff is friendly and helpful. They went out of their way to make sure I got a warranty part replaced. Their communication is professional and they completed the work in a timely manner and it looks wonderful! Thanks!
Bought step rails for a truck. Took less than an hour to have them installed! Great work!
Great service. Super quick install.
Love the new look
Eric was a pleasure to work with on my LEER top! Capable service guys installed my top and it looks great. Thank you!
Great experience!
My experience was great Brandon was exceptionally helpful and professional and the crew did a great job installing my tonneau cover Thanks
Tyler and his team have done a couple different jobs for me this year on two different trucks. The quality of work was outstanding.
Great service
Brian and his employees did an outstanding job!! upgrading my 2013 Ford F150 truck. His customer support,patience and fair pricing was really appreciated. I felt taken cared of & the result was excatly what I needed.
It’s great service here an good products to Choose from plus a great atmosphere.
The HH sales and install team were through the whole process of ordering, receiving and storage of my LEER topper and Decked slide out. I’m already looking at additional upgrades to my truck because of my confidence in their professionalism
Love my new bed cover! It looks amazing and will provide much needed protection for items I chose to put in the truck bed. Everyone was uber friendly! The bedliner I chose was reasonably priced and installation took less than 30 minutes. I will be spending more $$ there when I need some other truck accessories! Before and after pics of my truck bed.
The guys were thorough and detail oriented. They went to great lengths to explain the product and were Happ to any any questions.
Fast! My order was ready, and installed in less than 24hrs! (Would have been sooner but I had to wait till next day) Staff was very friendly, will definitely be back!
Luke went out his way to make sure we had enough space for the delivery for our new shed!! Thanks Luke! You're awesome!!!!!!!
I had a problem with a tonneau cover almost blowing off. I patched it as best I could and visited H & H in Muscle Shoals to see if they could fix it even though it had been installed at a different H & H store. Rusty was kind enough to fix it easily. Highly recommend this individual.
Had the pool parts we needed and a lot of other things!
Excellent service. Highly recommend!!
It was a good experience, everything went as we told, although a little delayed. The waiting room was however not comfortable and could have used a good deep cleaning and more comfortable seating. The bed liner we purchased was great but the store needs a little TLC!
Super great service No complaints at all
The men at H&M’s H were outstanding With great customer service. I will go back to the Andalusia H&H for any needs for my truck. Thank you for a great experience.
Always a pleasure dealing with the Pensacola H&H. Prices are very fair, schedules are kept, communication and status updates are great and their install team is top notch. I’ve had them perform installs on my 3rd & 4th Gen Tacomas, and now my 2026 Tundra. I could not be happier. Highly recommended!!
