early abody dougs d450 headers1 5/8" tubes .. 2.5 collector , Stock 65 dartcharger 273 .... Question is>>> what size headpipes off the headers would work the best with this engine? I have an old set up 2.5" headdpipes dynomax ultraflo muffs and 2.25 tails . do you think the 2.5 head pipes are tooo large ? or will work just fine .
This little engine does not have a lot of torque as you all know...... so I do not want to take all the bottom end away with big tube pipes.
