I have your exact combo and really like it. I am running a 12.25x3.75 APC and a MAC Header and 7.5cc Tuned Pipe.. I played around with mousse cans and did quite a bit of building, testing and research on them. IMO you cannot beat the MAC Header and Pipe set-up. Mount your engine as far forward as possible so your not too tail heavy.
You can do a search on my user name ((Dapped)in the Author criteria) and you will find lots of info and pics on my set-up
Cheers
