Fitment Note: Fits FXD, FXDC, FXDL, FXDWG only with passenger pegs removed.

• Traditionally viewed as the kind of pipe merely designed for performance, Big Radius 2-into-1 breaks the mold, delivering white-knuckle performance with the style that has won over the motorcycle public

• Incorporating blue-proof technology across the entire length of the pipe, Big Radius 2-into-1 will keep its showroom finish whether at the drag strip or on the boulevard

• The flat plane mounting panel, for the oxygen sensors, positions sensor deeper into exhaust stream, providing enhanced data feedback to the ECM

• Includes mounts for factory O2 sensors as required

• Repositioning of passenger footpeg, might be required

If your riding a Fat Boy order the optional left foot peg mounting bracket #443-576 to level the pegs or the right one will be higher after the install. FWIW

Pro's - Love the sound it makes on my Fatboy. It sounds like I have a werewolve growling in my garage. It looks great on my bike and gives it a more distinct and aggressive look. Con's - Passenger Foot-peg relocation raises the pegs about an inch to fit the pipes. Wife felt a bit cramp. Definitely more of a pipe for Solo Riders than two-ups on Softail's.

I love the look of 2 into 1 exhaust. I have a 2014 CVO Softtail Deluxe, V & H does not recommend these for my bike. I, however, was determined to make these fit. If you want to make them fit you'll need a left side relocation bracket, for even passenger foot pegs. Because of my saddlebag mount grommet I had to get new hardware, a hex top bolt for the bottom by grommet, and a shorter allen for the footpeg end. (2, one for each side) My O2 sensor Is 12mm, the pipes are 18mm, need 2 adaptor reducers. I found some by Bassani. The fitment is tight but everything clears. The pipes sound great. Kinda loud, with an amazing low rumble that reminds me of rolling thunder. There was also a noticeable power response increase.

Pipes were beautiful, unfortunately I didn't read the fine print in the catalog, wouldn't fit my soft tail with heritage bags. Sent them back hassle free. Awesome job J&P

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect.

• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.
