Exhaust and some other advice needed

I'm a new member to TW and i think this forum is great.
i have been wanting to upgrade my muffler for some time and have been reading through a lot of threads on this website that lead me to choose the flowmaster 40. but now i would like to get some advice on a new cat converter. i looked at JCwhitneys and didn't really learn anything. Any advice or recomendations would be greatly appreciated.
My truck is a 98 2.7L

 

I think the cherry bomb glass packs sound better and dont drone the sound in the cab. but I think magnaflow makes a hi-flow cat that will work.

 

Hit up cris4x4 for some advice. He had a 2.7l that he supercharged and he knows what he's talking about when it comes to getting the most out of any tacoma.
