The 100% NEW Thumper 2!!

Are you looking for the best flowing exhaust system for your trail 70 but want the stock look? This is an advanced design by Trail Buddy Inc. for the classic mini trail-70 and reproduction bikes. The Thumper 2 has an open flow design with a 1inch neck down outlet. We get the best low to top end performance with this combination. This is a new pipe manufactured for Trail Buddy.

This exhaust has been designed by us for maximum performance and sound.

Mounting Brackets

The Thumper 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.


The exhaust will fit the classic mini trail-70 bikes 1969 to 1994 and the reproduction bikes. If you are using this exhaust system with your stock skid plate and spark plug shield, the lower heat shield on the exhaust will need to be removed to clear the spark plug shield. The included heat shield can be replaced with a CT70 1972-1978 stock shield.

 Our customer supplied pictures of the demo Thumper 2 on his bike to show fitment.

This is perfect for larger engines and higher flow for more power with a great sound. Just look at the video ......... coming soon
