Noon Racing Chambered 2-1 Stainless Steel 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 expansion chambers (theoretically Heimholtz resonators). The expansion 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. They also help reduce some of the high pitch frequencies in the exhaust note.

A major focus point on these exhausts is the inside of the pipe. We build these with efforts to improve flow as much as possible. Featuring machined flange sets that start the exhaust off right at 1.875”, fully back purged welds to get zero burn through, and a semi polished INNER SURFACE of the tubing. When you get your exhaust from us, shine a flash light inside, you’ll see.

Features:

-Hand Built in the USA

-TIG welded and back purged

-Full 1 7/8” Primary Headers

-Sanitary Grade 304L Stainless Steel

-Several Build Options Available

Available in two different finishes, brushed or polished. The polished version is available with polished or rainbow welds.

Also available are two different mufflers, glass pack style or reverse megaphone (rebuildable).

Three different lengths are available, short, standard, and long (pictured: short).

Larger 18mm bungs are available for tuning focused builds (requires a reducer). 12mm is the standard size on FXD Harley Davidson.

This pipe will fit most FXD 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 stock Harley Davidson tapered exhaust gaskets and mounting hardware.

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. We try to get these exhausts out within 3-4 weeks. Though with building interest, it may take longer.
