I have a murray minibike with a h35 45776y engine. I purchased a brute power pipe for it directly from brute power pipes, but it doesn't fix correctly. link to exhaust- Brute Power Pipes (it's the bpbm2). the bolt holes on it are farther apart then the bolt holes on my minibike engine. does anyone know where i can get a after market pipe that will fit my minibike?
