I have a newly built 421cc cub with 35 keihin carbs and t-5 exhaust. My problem is the t-5s don't fit on the exhaust ports that well and the exhaust on the driver's side is almost touching the carb and does touch the fuel line! No way to move the fuel line because it is where the fuel inlet is. I am thinking of going to another set of pipes, but was hoping to use the t-5s. Any thoughts on the t-5s? Any suggestions on the new pipe possibilities and anybody know what will fit? Let me know. Thanks, Matt
