Well I decided to gut the cat on my Hawk. Just cut out a "window" and it pretty much just popped out. Welded the "window" back in, checked for leaks and painted. I also got froggy and made a new insert for the muffler. Went up to 1 1/2 inch pipe. Made the insert using EMT conduit and a 4" square electrical box cover (being an electrician stay with what you know). Sounds deeper and a little louder but not much louder. Can definitely tell a difference in power as it gets to 55 faster/easier and cruise's at 50 effortlessly. I need to get a long drill bit and drill some holes in the baffle in the muffler to free up some more flow and then will probably re-jet again. Pretty good mod for under $20. Here are some pics.
