Yes and no, depends on the distance between header and pipe. To short distance, out of the manufacturers range, could cause engine overheating.
But plug type, nitro %, gearing, and total head chamber (shims) would most likely be the cause.
You would have to be more specific. What pipe are you running, with what engine, what nitro%, what plug N°, what chamber shimming.
