Interchangeable Endcap Design

Thanks to their proprietary FAB28 modular muffler design, they allow for a further level of customization with each motorcycle exhaust. Easy to change endcaps allow you to personalize your exhaust system with the endcap that best fits your style.

From Fab28:

“From idle to redline, FAB28 Industries is committed to providing a sound that stands out from the crowd. Our exhausts sound unlike anything else on the road thanks to our proprietary designs, countless hours of R&D, and our commitment to quality. But, great sound without great performance is just a gimmick, and we don’t do gimmicks. Our free flowing exhausts have essentially none of the restrictive qualities of stock systems. The result? We’ve see gains of up to 8% over stock exhaust systems after installing a FAB28 exhaust!

All of our exhausts are constructed from the highest quality 304 stainless steel 16 gauge tubing to ensure that you can run your motorcycle like it was meant to be run. All of the sections of our modular exhaust system are fabricated in our California shop and then carefully assembled by hand and welded by experts to ensure proper fitment. By assembling our exhausts in a modular way, we can reduce stress on the metal which in turn eliminates cracking and gives you an overall more durable product.

We source all of our steel from within the United States so you can be sure that the metal being used to fabricate your exhaust is of the quality you expect. Every FAB28 exhaust system is tailor made to fit each bike and its characteristics. Therefore, we do not recommend installing FAB28 systems on bikes they are not intended for.”

Current product lead time is 4-6 weeks. Additional time needed for black ceramic coating.
