I have a crack in my Cat and I was wondering if anyone know what would be a good patch to use on a cat for rotary engines? I know welding would be best but I don't have anything like that. Is there something I can use to patch it up?

 

I would only weld...Or if you had the bucks, racing beat sells their header kit for 100 dollars, then you could have a local shop wrap it up for you. One shop in my area does stuff cheap, unlike the other places that wanna gouge for everthing.....

 

i beleave i have a test pipe from my old set up...it will free up hp and drop a lil bit of wight.only down side is you wont have a cat lol ill look for it if you think you might want it
