Jerry, do you have a suggestion for a Silencer that will work with the PT pipe?

Say like a FMF turbo core or a JH special made or something?

I would not use the FMF spark arrestor model unless you absolutely have to.  The spark arrestor insert adds considerable back pressure  The FMF straight through silencer with the 1 3/8" OD mid pipe works good up to 60 to 65 hp then you need to cut off and replace the small short stinger that connects the tail cone with the mid pipe with 1 3/8" OD 18ga tubing.
