 to use yetyet)3.70 rear gear. Will that be too large diameter
 pipe...full exhaust all the way out the back? I don't want to defeat
 the purpose of my large exhaust by using too large and hurting the
 scavenging affect!I may be able to swap them for 2 1/2" when they make
 up my dual exhaust after i get the 401 
installed.Thanks,Joe
