## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [Japanese Mini Bike Parts > CRF100 and XR100](https://tboltusa.com/store/japanese-mini-bike-parts-crf100-and-xr100-c-100_62.md)
- [TB Parts > XR100 CRF100](https://tboltusa.com/store/tb-parts-xr100-crf100-c-68_80.md)

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## Description (the store's own text)

**NOTE:** Exhaust does NOT have mounts for original exhaust guard.

Why should big bikes get all the attention?
With the Mini PowerCore 4 you can finally bring advanced exhaust engineering to the smallest bike in your garage. A Hi-Flo stainless steel core formed end caps and header are just three of the reasons why this system is light-years ahead of every stock play bike exhaust out there. Bolt it on fire it up and go enjoy major performance gains at a price you can afford.

**Key Features:**

- Several pounds lighter that stock
- Incredible performance at a great price
- Hi-Flo stainless steel core and formed end caps with aircraft grade aluminum canister
- Full systems include durable stainless steel header
