RPM Pro R "Big Core HeadPipe" Header Pipe
The Pro R’s stock head pipe is an efficient design but is limited by mass-production flaws and being built for a restrictive factory muffler.
The RPM Big Core HeadPipe is a direct bolt-on upgrade that keeps the stock heat shield and works with factory or aftermarket mufflers, while improving exhaust flow through smoother internals, larger and better-matched pipe diameters, and a redesigned 4-2-1 collector.
It also improves frame and tire clearance, retains the factory O2 sensor, adds an extra O2 bung for tuning, and includes heavy-duty hardware, making it a refined replacement that corrects the OEM compromises without changing fitment.

- Brushed 304 Stainless
- Fully Tig Welded
- Highly Efficient Collectors
- OEM Fitment & Uses OEM Gaskets
- Retains Factory Heat Shield
