Hi just wondering if any one out there may have installed or knows of a high performance exhaust available for a 0-235 C1 lycoming engine available for a wagaero cub that is reasonably priced keep in mind it does not have to be certified. Also does anyone have any experience with these exhausts and did you notice any significant performance changes I am installing the high compression pistons in my cub so thought this may be a mod worth adding, if anyone has any info. it would be greatly appreciated. Thanks!
