When you throw in the durability part, I'm not sure if i was building my own I'd use M/S anymore, especially if you're spraying. Specifically for your application, the general pathway of "UP and OVER" then out the fender might be the best. You could error on the small side of pipemax if the lengths are shorter and the trajectory is nice. Thanks for all the additional pics that have been added! I have a decent inventory of bends yet but, apparently the materials cost has gone up a bunch. That may be your deciding factor. So, you're saying your old headers that served you well are for sale in the for sale section!?
