For decades, Fabspeed has led the industry with our performance products for Porsche, Ferrari, Lamborghini, McLaren, and other high end marques.

Now that our team includes several BMW owners, BMW club-racers, and former BMW employees, we are excited to be taking what we’ve learned over the last 20+ years and applying that experience and technology towards designing and fabricating performance exhaust products for the Ultimate Driving Machines.


Our product development inspiration comes from many different sources. For some projects, our marketing and R&D teams take the reigns. In other cases, we rely on our customers to tell us what they want, and we set out to fulfill those requests. Such was the case when a local Bimmerpost forum member stopped by with a request: spice up the exhaust note of his 2015 M3 which was already equipped with an M-Performance rear muffler. We worked with Matt to bring this product to life for the community. Our design includes dual x-pipe sections for optimal flow blending (also utilized on our full M3 & M4 Valvetronic Exhaust System) and a unique flex bellow which allows for straightforward installation.


If you aren’t familiar with the pinnacle of our BMW lineup, it’s high time you get acquainted.

When the BMW community came to us looking for additional tip options, we tasked our fabrication shop with producing a sleek, track oriented variant that we would make right here in-house. We crafted the Single Wall Brushed Quad Tips to complement the more aggressive carbon fiber aftermarket diffusers while offering adjustment that allows the tips to be set at a desired depth within the bumper. Producing these in-house allows us to make them at a custom length to match any setup.


We’ve taken on a new Performance Specialist, Bobby, who hails from a BMW background and has an M235i and 335i with which we developed a new system for.

Our Muffler Bypass Exhaust isn’t winning any awards for Most Complicated Design, but it’s leading the pack in contention for Most Grin-Inducing Sound. This is our easily reversible, weight reducing, sound enhancing, cost effective exhaust solution for the F3x 335 & 435 models.


The addition of a performance downpipe encourages a symphony of crackles and burbles on command.


Fabspeed is the largest distributor of HJS catalysts in the US, and second largest in the world! Our experience with pairing the correct cell count, duration, and diameter with specific vehicle applications has paid off. After much R&D, we are one of - if not the only - company providing a 200-cell high flow catalyst-equipped performance downpipe for N55 engine cars that does not trigger a check engine light. We also offer HJS’s own 300-cell Euro 6 compliant downpipe in addition to our Catbypass Downpipe to cover anyone's needs.


Our enthusiasm and passion to drive new innovation doesn’t stop at BMW. We apply these same processes to all of the makes and models that we work with. Thank you for reading about our BMW development, subscribe for future features on more marques!
