## 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.

- [Honda Vintage Mini Bike Parts > CT70 > Exhaust](https://tboltusa.com/store/ct70-exhaust-c-101_91_562.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)

This is a brand new replacement exhaust for the classic mini trail 70 and reproduction trail 70. This is a complete exhaust assembly, and is made from a good thick steel to stand up to long use. Excellent economical choice for Lifan & Piranha engine swaps too!

**Mounting Brackets:** The exhaust mounting tab over the shock is bigger to fit aftermarket shocks and gives more room for the stock setup. For the small mounting tab by the engine, we have had no problems. We find this helps fit more makes of engines, from the head to the mounting tab by the shock.

**Note:** The exhaust does not include a new gasket, but we have them available under part number TRC-1189.

**Application:**

- All model year CT70's and all replicas

**Specifications:**

- Header OD - 25mm
- Header ID - 19mm
- Exhaust mount at head center to center bolt spacing - 45mm
