- 2-into-1 Pro-Pipes are the systems Byron Hines developed when Vance & Hines decided they wanted to make the absolute best-performing pipe on the market for Harley motors
- Meticulous engineering - a hand-made race collector and specifically designed head pipes produce maximum scavenging of spent exhaust gasses, then a special baffle system provides just the right sound
- The collector is virtually Blue-Proof with its own full coverage heatshield
- True full-length 220 degree wrap heat shields on head pipes perfectly match the collectors heat shield
- Removable baffle and all mounting hardware included
- Made in the U.S.A.
- Not for kickstart models
- May not fit some models that have replacement driver floorboards
- For replacement end cap order H44-339, replacement standard baffle order H44-335, for optional competition baffle order H44-718
NOTE:
There is no warranty on exhaust pipes and mufflers with regard to any discoloration.
Discoloration (blueing)is the result of tuning characteristics, cam timing, carburetor jetting, overheating,etc. and is not caused by defective manufacturing.
See lubrication products for products that will help prevent or remove blueing.
For the best performance, a free-flowing air cleaner and carb re-jet kit or adjustable fuel management system is recommended with this pipe. Dennis Kirk recommends a speed's performance speedyflow air cleaner for most models. See 18-3336 for 93-99 EVO carb models or 18-3337 for all twin cam models
