Last summer the right flange on the Keleo exhaust header on my OS 160FT broke off. It was hard to see inside the DPM Super Cub cowl, but I noticed the pipes wiggling and making contact with the cowl exit hole. Has anyone else had this problem? Anyway, I contacted Keleo, they said send it back with $10 bucks and they would repair it. I finally got a round tuit and sent it in last week. Just got it back (less than a week turnaround) and....IT'S A BRAND NEW ONE! This one has beefier flanges on it and looks like it will last forever. Thanks to Keleo for some really great service!
