WHat is the best method to determine where the pipe should go? I have heard of guys painting a white stripe from the headers back on the underside of the pipe. Drive it until it burns off then look to see where the paint stopped burning. This is the spot to put the H pipe. Anyone ever tried this or is it an old wives tale?
Just put the crossover where it fits the best. That old locating method was thoroughly tested a couple years ago by one magazine and found to be irrelavent, since every rpm and throttle setting moves the melting/burning point around.
Thanks, that is a good link listed above.
