60ft is a 1.33 so far....on DOT "tires"...

Take the mufflers and exhaust off and open it to 3.5" wide open....Same ET.


It seems that a full 3" exhaust is capable to support big motors and HP, so I don't have to worry about that.... grin


I think the muffler matters more than going to bigger than 3"...Personally, the best sounding and best performance mufflers I like are the Spintech ones with their oval exhaust. Get the best of both worlds...
