2-1 Low Pipes for Air Cooled Bonneville and Thruxton

The 2-1 Low Pipes are now available with sweeping bend headers for a vintage look that will patina well over time. Handcrafted out of 100% stainless steel and TIG welded then brushed for a custom, raw appearance. A track ready system engineered to get you off the line and down the back straight, ahead of the pack. The right side of your bike is completely exposed: the alternator case, sprocket cover, and driveline deliver form via function while the right side header crosses over to the left to merge into a 2-1 collector with three piece in total. The brushed stainless system will develop a lustrous pattern over time, creating a raw performance look.

Note: Removal of O2 sensors required on EFI models. This performance upgrade requires tuning of your motorcycle. Not compatible with a center stand.

Q: Do I have to retune my bike after installing this system?
A: A remap will be required and typically, the 2-1 Arrow MAP is a good starting point; we recommend getting this installed through your local dealer

Q: Is is normal for the system to slightly change color with time and use?
A: Yes, the brushed Stainless Steel (304) will develop a nice raw look over time; almost like selvedge denim!
