How Do I Know If Thunder Monster Baffles Will Fit My Pipes?

Big City Thunder products work in any 4 cycle engine with a straight pipe type exhaust from a single cylinder up to 6 cylinder motorcycles with any cubic inch displacement. Installation instructions are included with all our products.

If you have Vance & Hines, Screamin' Eagle, Bub, Cobra, Samson, Tab Performance, Rinehart, Jardine, Bassini, Custom Built, or other aftermarket pipe that at the exit end does not turn out (does not include tips that can be removed), and is of a straight type pipe design that measures
1 5/8", 1 3/4", 1 7/8", 2" or 2 1/8" inside diameter, Thunder Monster baffles will fit your pipe.

For curved pipes such as Vance & Hines Big Radius and Ness Slashers we recommend our Thunder Monster baffles part number 2002. For the Hooker Troublemakers we recommend our Thunder Monster baffles part number 2001. For other curved pipe applications please call and have the pipe dimensions available.

* All prices subject to change with out prior written notice.

DUE TO THE FACT THAT PIPES AND STYLES WILL VARY EVEN WITH THE SAME MANUFACTURER PLEASE BE SURE TO MEASURE THE INSIDE AND OUTSIDE DIAMETER OF YOUR PIPES AS WELL AS THE OUTSIDE DIAMETER OF YOUR BAFFLE, PROVIDED YOU HAVE ONE, BEFORE CALLING OR E-MAILING; WE NEED THAT INFORMATION IN ORDER TO PROVIDE YOU WITH THE CORRECT PRODUCT.
