Dyna® Chamber Short Exhaust (Twin Cam FXD)
What started as an experiment to bring some motocross technology into the Harley world, is now available to the public.
This 2-1 stainless exhaust is equipped with two resonator chambers (theoretically Helmholtz resonators). The resonator chambers have several impacts on the exhausts performance. The main benefit being a broad power band. These chambers will spread out a peaky power band to a broader range of RPM’s. Dyno tests have shown that these chambered pipes perform up to 10% better than the leading competition 2-1 exhausts. Typically these chambers will give you a significant boost in torque that will come on earlier and stay high and smooth throughout the RPM range. They also help reduce some of the high pitch frequencies in the exhaust note.
Features
-Hand Built in the USA
-TIG welded and back purged
-Full 1 7/8” Primary Headers
-All necessary hardware included (including gaskets)
-Sanitary Grade 304L Stainless Steel
Also available are three different mufflers, glasspack style, megaphone (rebuildable) or full (rebuildable). Pictured: Megaphone
This pipe will fit most FXD Twin Cam Dyna models from 1994-2017 with Mid Controls and Further Forward Mid Controls. Some larger air cleaners may hit the chamber. All pipes come with transmission mounted brackets and stainless hardware. The pipe uses flat style exhaust gaskets.
Due to the fact that this is a one man company, and that these are hand built systems that are made to order, wait times will vary. I try to get these exhausts out within 8-10 weeks. Though with building interest, it may take longer. Full payment is required up front. Refunds are available within reason.
