I know it's a truggy engine, but I plan to use it as a back-up motor in my
buggy.(don't own a truggy) What header/pipe combo would be best for a buggy? Twister mentioned short header and the 9901 pipe. I have a 9886 pipe
with the 41021 short manifold on my 21-5k will this combo work on the FMS?
Also whats the differents between the 9901 and the 9853 they look the same?
